Chevrolet Camaro restoration — 1967-onward through 1992-onward across first-gen F-body 108" (Z/28 + ZL1), second-gen 1970–1981 unibody rollover, third-gen 1982–1992 + IROC-Z, and the pre-1973 holdouts.
The Chevrolet Camaro nameplate spans the 1967-onward through 1992-onward GM F-body 108-inch-wheelbase unibody across three engineering generations: the 1967-onward first-generation F-body (the 1967-only door-jamb trim tag, the 1968-onward Fisher cowl tag, the 1967-onward Z/28 DZ 302 small-block with the Z-code stamped on the cowl tag, the 1967-only Z22 Rally Sport hideaway-headlight package, the 1967 launch-year L30 327 base / L35 396 / L78 396 progression, the LS-series 396 L34 / L78 / L89 chain on the 1968-onward 3963512 block, the 1969-only ZL1 all-aluminum 427 COPO 9561 fitment, the 1970 split-year Z/28 DZ 302 carryover on the second-gen launch-year first-gen chassis build, and the 1970 LS6 454 / 1971 LS5 454 / 1972 LS4 454 / 1973 LS4 454 SS option chain); the 1970-onward second-generation F-body (the unibody-shared body-shell rollover, the 1974-onward Type LT luxury trim package, the 1977-onward Z28-only-second-gen layer); and the 1982-onward third-generation F-body (the third-gen hatchback body style, the 1982-onward Berlinetta luxury-coupe trim, the 1985-onward IROC-Z RPO Z6C race-prepped trim, the 1987-onward convertible return, the 1985-onward L98 TPI 350 V8 fuel-injection, the 1988-onward 5.7 L LB9 TPI V8 fuel-injection, and the 1991–1992-onward WX3 / WX4 cross-fire fuel-injection cowl-tag layering). The pre-1973 holdout triplet is the authentication chain for pre-1973 cars: the 1967-only door-jamb trim tag schema, the 1969-only ZL1 COPO 9561 single-model-year fitment, the 1970 split-year Z/28 DZ 302 carryover. Cross-marque engine-swaps misrestore at the engine level — a Camaro chassis with a Pontiac 303 / Olds 350 / Buick 350 cylinder head does NOT seal a Chevrolet small-block combustion chamber.
Eight 1967-onward through 1992-onward Camaro authenticity discriminators — the same engineering facts the brand-hub preview carries so the two surfaces never drift.
- 1. The 1967-onward first-generation Camaro Z/28 is the Chevrolet-side homologation fitment built to race the SCCA Trans-Am series — identified by the Z-code stamped on the cowl tag (the Z- prefix ordering code that authenticates the Z/28 fitment from the assembly plant forward) and authenticated against the cowl-tag broadcast sheet. The Z/28 runs the DZ-coded 302-cubic-inch small-block V8 (casting 3892657 with K-suffix date-code stamp); it does NOT run the X77-coded 396-base engine that defined the SS 396 Camaro. The X77 prefix is a different fitment — an SS-equipment Camaro with the X77-coded 396-base, NOT a Z/28. Reading an X77 ordered chassis with Z21 stripes cosmetically applied does NOT authenticate a Z/28; the cowl tag Z-code is the discriminator, not the stripes.
- 2. The 1967-onward first-generation Camaro rides on the GM F-body 108-inch-wheelbase Camaro unibody — a chassis family shared with the SS 396 Camaro, the base Camaro, and the Rally Sport Camaro (the RS package was a separate RPO D80 Hideaway Headlight fitment). The Camaro F-body chassis is distinct from the GM A-body Chevelle 112-inch-wheelbase unibody, distinct from the C3 Corvette stub-frame, distinct from the Chevy II / Nova 400 F-body-but-X-platform chassis. The Z/28 on a Chevy II / Nova 400 chassis would be a Chevy II / Nova 400 trim swap, NOT a Z/28. The F-body Camaro wheelbase and unibody shell carries the Z/28 documentation track, NOT a Chevy II / Nova wheelbase.
- 3. The Z21 stripe option code is a Z/28-stripes RPO code (the white "Z" hockey-stick stripes over the hood and rear deck) — a Z/28-standard fitment, NOT a cosmetology add-on. The 1967-first-year Camaro carried Z21 stripes in white over the Rallye Green / Butternut Yellow / Nantucket Blue codes; the 1968-onward carried Z21 stripes over the all-Z/28 color set. The Z21 stripes authenticate the visual Z/28 trim callout, but the cowl-tag Z-code authenticates the engine / option track at the assembly-plant level. A Z/28 chassis without the Z21 stripes is mis-restored at the visible-trim level; a base Camaro with Z21 stripes cosmetically painted is mis-restored at the option-code level.
- 4. The 1969 Z/28-only Hideaway Headlights (RPO D80) and the 1967-onward Z/28-standard Positraction rear (RPO G80) are documented at the part level. The 1969 Z/28 carried the Z/28-specific aluminum intake manifold with the Holley 780-cfm list #4150 carburetor (the documented Z/28-only carb / intake combination for the 1969 model year). The 1967–1968 Z/28 carried the Z/28-specific cast-iron intake with the Holley 780-cfm list #4150 carb (the 1967–1968 Z/28-only spec). A 1969 Z/28 with the cast-iron intake from the 1967–1968 spec is mis-restored at the induction level; a Z/28 with an open rear axle reads as mis-restored at the differential level.
- 5. The 1967-only door-jamb trim tag vs the 1968-onward Fisher cowl tag is the year-specific discriminator at the documentation-tag level — the 1967 launch-year Camaro shipped with a door-jamb-mounted identification plate (a door-jamb trim tag stamped with the Fisher body code, body style code, paint code, trim code, build plant, and Year-Plus-Week sequence), while the 1968-onward Camaro adopted the standard Fisher Body cowl tag (mounted on the cowl under the hood, with the same fields in a layout that became the Chevrolet standard through the 1973-onward first-gen close and persisted into the 1974-onward second-gen and the 1982-onward third-gen). A 1967 Camaro chassis reading against a 1968-onward Fisher cowl tag reads as mis-documented at the trim-tag format level; a 1968-onward Camaro chassis with the 1967-only door-jamb trim tag schema reads as mis-formatted at the trim-tag format level. Cross-check the trim tag location AND format, not just the chassis year.
- 6. The 1969-only ZL1 all-aluminum 427 COPO 9561 single-model-year fitment is documented by FOUR ZL1-only hardware items: the ZL1-only all-aluminum 427 short block (a Chevrolet-side aluminum 427 block casting distinct from the cast-iron 3963512 L72 427 block code, the all-aluminum 427 was lighter than the cast-iron L72 by approximately 100 lbs), the ZL1-only aluminum heads with the rectangular-port casting (a documented ZL1-only head casting distinct from the L78 cast-iron oval-port head), the ZL1-only Holley 4150 list #4153 780-cfm carburetor (the ZL1-only carb calibration, distinct from the L78 cast-iron intake carb), and the 1969-only COPO 9561 Central Office Production Order order code stamped on the cowl tag TO-code prefix. The ZL1 was built in quantity 69 units for the 1969 model year — cross-check the cowl tag TO-code prefix against the build sheet, not against the engine-stamped block code alone. A 1969 ZL1 chassis without all four ZL1-only hardware items is mis-restored at the engine level.
- 7. The 1970 split-year Z/28 DZ 302 carryover is the engineering artifact that defines the second-gen launch-year first-gen chassis build authentication chain — the 1970 model year carried both the first-gen Z/28 (the 1970 Z/28 in the F-body first-gen carryover mode, sold alongside the 1970-onward second-gen Camaro launch) AND the 1970-onward second-gen Camaro body shell. The 1970 split-year Z/28 DZ 302 carryover is the same DZ-coded 302 small-block (casting 3892657, K-suffix date-code stamp) on the same first-gen F-body 108-inch unibody chassis — distinctly NOT the 1970-onward second-gen Camaro. Reading a 1970 second-gen Camaro chassis against a 1970 split-year Z/28 documentation reference reads as mis-documented at the chassis-generation level.
- 8. The 1985-onward IROC-Z RPO Z6C race-prepped trim package is the third-gen-only homologation fitment — the IROC-Z is a TRIM package (not a separate model line) layered on top of the third-gen Camaro body shell, with the RPO Z6C ordering code on the build sheet paired with the 1985-onward L98 TPI 350 V8 (or the 1988-onward 5.7 L LB9 TPI V8, where fitted) fuel-injection powertrain. The IROC-Z carries the Z6C-specific 16-inch alloy wheels, the Z6C-specific front / rear spoilers, and the Z6C-specific decals — distinct from the base third-gen Camaro. Reading a third-gen Camaro chassis with the Z6C trim package cosmetically applied (the decals only, NOT the 16-inch wheels, NOT the Z6C-specific spoilers) reads as mis-restored at the trim-package level; the RPO Z6C build-sheet ordering code is the discriminator.
Year-by-year model breakdown
The 1967-onward through 1992-onward Chevrolet Camaro — twenty-six model years.
One card per model year from the 1967 launch-year first-generation with the 1967-only door-jamb trim tag (NOT the 1968-onward Fisher cowl tag), through the 1969-only ZL1 COPO 9561 all-aluminum 427 single-model-year fitment, the 1970 split-year Z/28 DZ 302 carryover on the second-gen launch-year first-gen chassis build, the 1970 LS6 454 / 1971 LS5 454 / 1972 LS4 454 / 1973 LS4 454 SS option chain, the 1974-onward second-gen rollover with the Type LT luxury trim and the 1977-onward Z28-only second-gen window, and the 1982-onward third-gen with the Hatchback + Berlinetta + 1985-onward IROC-Z RPO Z6C race-prepped trim and the 1987-onward Convertible return + 1985-onward L98 TPI 350 V8 / 1988-onward 5.7 L LB9 TPI V8 fuel-injection + 1991–1992-onward WX3 / WX4 cross-fire fuel-injection cowl-tag vector. Each card carries the engine / RPO notes, the body styles offered, and the model-year landmark.
Launch-year of the 1967-onward first-generation Camaro on the GM F-body 108-inch-wheelbase unibody. The 1967 Camaro is identified by the 1967-only door-jamb trim tag (NOT the 1968-onward Fisher cowl tag) — the door-jamb-mounted identification plate carries the Fisher body code, body style code, paint code, trim code, build plant, and Year-Plus-Week sequence. The 1967 launch-year engine lineup runs the L30 327 base / L35 396 / L78 396 (the 1967-only 3963512 L78 396 / 375 hp, distinct from the 1968-onward L78 castings). The Z/28 fitment debuts in 1967 with the DZ-coded 302 small-block (casting 3892657, K-suffix date-code) carrying the Z-code ordering prefix on the cowl tag, the Z21 stripe option code, and the 1967 Z/28-only Holley list #4150 780-cfm on the Z/28-specific cast-iron intake. The 1967-only Z22 Rally Sport hideaway-headlight package is a separate RPO Z22 fitment distinct from the Z/28 — a 1967 RS-equipment Camaro with a Z/28 stripe set is mis-documented at the option level. The 1967 Camaro carries the 1967-only X77 trim-tag discriminator on the SS 396 paths.
Engine + RPO notes
1967 L30 327 base / L35 396 / L78 396 (3963512 block, 1967-only). 1967 launch-year Z/28 DZ 302 small-block with cast-iron intake + Holley list #4150. RPO Z21 (Z/28 stripes), Z22 (RS Hideaway headlights), Z28 (Z/28 fitment), L78 (396/375 hp), D80 (Hideaway headlights option), G80 (Positraction standard on Z/28).

The 1968 Camaro rides the F-body 108 with the 1968-onward Fisher cowl-tag standardization (the 1968-onward cowl tag replaces the 1967-only door-jamb trim tag). The 1968 Z/28 DZ 302 carries on with the same DZ-coded 302 small-block (casting 3892657, K-suffix date-code stamp) on the Z/28-specific cast-iron intake with the Holley list #4150 780-cfm carb. The 1968 SS 396 brings the L34 350 hp and L78 396/375 hp fitments open on the 1968-onward 3963512 block. The 1968 Camaro carries the first year of the 1968-onward Fisher cowl tag format, which becomes the Chevrolet standard through 1973-onward first-gen and persists into the 1974-onward second-gen and the 1982-onward third-gen. Cowl tag decodes against the 1968-year-specific letter-pair codes — distinct from the 1967-only door-jamb trim tag letter-pair codes.

Landmark: 1968 Fisher cowl tag standardization replaces 1967 door-jamb trim tag + L34 350 hp 396 + Z/28 DZ 302 carryover.
The 1969 Camaro anchors the 1969-only ZL1 all-aluminum 427 COPO 9561 single-model-year fitment — 69 ZL1s built, documented by FOUR ZL1-only hardware items: the all-aluminum 427 short block (lighter than the cast-iron L72 by approximately 100 lbs), the aluminum heads with the rectangular-port casting distinct from the L78 cast-iron oval-port, the Holley 4150 list #4153 780-cfm carburetor, and the 1969-only COPO 9561 Central Office Production Order order code stamped on the cowl tag TO-code prefix. The 1969 Z/28 carries the Z/28-specific aluminum intake manifold with the Holley 780-cfm list #4150 carburetor (the documented 1969 Z/28-only carb / intake combination) — distinct from the 1967–1968 cast-iron intake spec. The 1969-only Hideaway Headlights (RPO D80) is documented as a Z/28 option distinct from the Z22 Rally Sport package. The 1969 1968-onward Fisher cowl tag format continues.
Engine + RPO notes
1969-only ZL1 all-aluminum 427 COPO 9561 (aluminum short block + aluminum heads + Holley 4150 list #4153 + cowl tag TO-code). 1969 Z/28 DZ 302 with aluminum intake + Holley list #4150 (distinct from 1967–1968 cast-iron spec). 1969-only Hideaway Headlights (D80) Z/28 option. 1969 SS 396 L34 / L78 carryover.
Landmark: 1969-only ZL1 all-aluminum 427 COPO 9561 single-model-year fitment + Z/28 aluminum-intake swap + D80 1969-only option.
The 1970 Camaro closes the muscle-peak window on the F-body 108 — and is the 1970 split-year Z/28 DZ 302 carryover on the second-gen launch-year first-gen chassis build. The 1970 model year carries both the first-gen Z/28 (the 1970 Z/28 continues on the first-gen F-body 108 chassis, sold alongside the 1970-onward second-gen Camaro launch) AND the 1970-onward second-gen Camaro body shell. The 1970 split-year Z/28 DZ 302 carryover is the same DZ-coded 302 small-block on the same first-gen F-body 108-inch unibody chassis — distinctly NOT the 1970-onward second-gen Camaro. The 1970 LS6 454 / LS5 454 / L78 454 in 1970 carry on the SS option chain. The 1970 SS 396 (X77-prefix base) and the 1970 ZL2 cowl-induction hood option authenticate the muscle-peak SS 396.

1970 split-year Z/28 DZ 302 carryover on the first-gen F-body 108. 1970 LS6 454 / LS5 454 / L78 454 in 1970 SS option chain. 1970 ZL2 cowl-induction hood option. RPO Z7A (cowl induction), Z11 (drag pak 1969-only carryover in some 1970 build sheets), D80, G80.
Landmark: 1970 split-year Z/28 DZ 302 carryover on second-gen launch-year first-gen chassis build + LS6 / LS5 / L78 454 SS option.
The 1971 Camaro is the second-gen full-year — the second-generation F-body 108 in standard unibody-shared body-shell production. The 1971 LS5 454 carryover (the 1970 LS6 454 retirement) on the A-body shared chassis distinct from any first-gen 1970-onward LS6 configuration. The Z/28 fitment carries on as a 1971-onward second-gen layer — NOT a 1970 split-year carryover. The 1971 Camaro cowl tag decodes against the 1971-year-specific letter-pair codes (the 1971-onward second-gen format).
Engine + RPO notes
1971 LS5 454 carryover (1970 LS6 retirement). Z/28 second-gen fitment. Cowl tag decodes against 1971-year-specific letter-pair codes (second-gen format).

Terminal model year for the first-generation Camaro on the F-body 108-inch-wheelbase unibody. The 1973 LS4 454 carryover with the 1973-onward emissions-era terminals: lower compression, thermostatic air cleaner, evaporative emissions control, exhaust gas recirculation. The 1973 Camaro is the last first-gen year — the 1974-onward second-gen shell is the rollover.
Engine + RPO notes
1973 LS4 454 carryover (emissions-era terminals). First-gen terminal year. Cowl tag decodes against 1973-year-specific letter-pair codes.
Landmark: 1973 first-gen terminal year + LS4 454 emissions-era terminals.
1974-onward second-generation Camaro body-shell rollover. The 1974 second-gen Camaro establishes the new body style distinct from the 1973-onward first-gen close. The 1974-onward Type LT luxury trim package debuts. The 1974-onward second-gen Z28 launches as a 1974-onward body-style-specific trim layer distinct from any first-gen Z/28. Cowl tag decodes against the 1974-year-specific letter-pair codes (1974-onward second-gen format).

Engine family & RPO guide
Chevrolet F-body engine family — 302 DZ Z/28 + 327 L30 + 350 LU + 396 LS-series + 1969-only ZL1 + 454 LS5 + 1982-onward 305 LG4 + 1985-onward L98 TPI 350 + 1988-onward 5.7 L LB9 TPI fuel-injection.
The Chevrolet-side engine family authentication chain — cylinder head bolt-pattern, balancer pattern, and the 1967-onward DZ 302 Z/28 cross-bolt mains, the 1968-onward 3963512 L78 396/375 hp, the 1969-only ZL1 all-aluminum 427 COPO 9561 single-model- year fitment, and the 1985-onward L98 TPI 350 + 1988-onward 5.7 L LB9 TPI fuel-injection powertrain layering. The Chevrolet castings do NOT interchange with any Pontiac 303 / Olds 350 / Buick 350 / Pontiac Ram-Air 400 / Chevrolet big-block 396/427 marque-cross engine — the cylinder head bolt-pattern and balancer pattern are Chevrolet-only at the casting level.
The 1967-onward through 1992-onward Camaro engine family — twelve displacement families on the Chevrolet-side castings distinct from any Pontiac / Olds / Buick marque-cross engine.
GM F-body 302-cubic-inch DZ small-block (Z/28 castings 3892657 K-suffix)
1967-onward · 1967-onward Z/28 small-block — the Z-code stamping on the cowl tag authenticated the Z/28 fitment.
Chevrolet-side 302-cubic-inch DZ small-block V8 — the Z/28 homologation fitment castings 3892657 with K-suffix date-code stamp. NOT the X77-coded 396-base SS 396 Camaro engine. The DZ 302 small-block Chevrolet-side fitment is distinct from any Pontiac 303 / Olds 350 / Buick 350 — the cylinder head bolt-pattern and balancer pattern are Chevrolet-only at the casting level. A Camaro Z/28 chassis with a marque-cross engine swap reads as mis-restored at the engine level.
L30 327-cubic-inch small-block
1967-launch-year · 1967 launch-year base V8 standard fitment
Chevrolet-side 327-cubic-inch small-block V8 launched as the 1967 launch-year standard V8 on the F-body Camaro. The L30 327 casting is distinct from any first-gen 302 / 350 / 396 / 427 — Chevrolet-side castings only. Reading a 1967 launch-year Camaro with the L30 RPO absent from the build sheet reads as mis-ordered at the base-engine level.
LU 350-cubic-inch small-block
1968-onward · 1968-onward base 350 small-block standard fitment on the F-body Camaro
Chevrolet-side 350-cubic-inch LU small-block — the 1968-onward standard fitment on the F-body Camaro chassis. The 350 LU casting is the 1968-onward Chevrolet-side small-block; distinct from any Pontiac / Olds / Buick castings. The 1968-onward Chevrolet 350 carries the 350-fired cylinder head bolt-pattern + balancer pattern Chevrolet-only.
LS-series 396-cubic-inch big-block (L35 / L34 / L78)
1968-onward · 1968-onward SS 396 base 350 hp / 1968-only L78 396/375 hp fitment chain
The 1968-onward LS-series 396-cubic-inch big-block on the F-body Camaro runs the L35 325 hp base, the L34 350 hp 1968-onward fitment, and the L78 396/375 hp 1968-onward SS-option. The L78 396/375 hp is documented at the cowl tag L78 RPO code on the 1968-onward cowl tag — NOT the engine-stamped block code alone. The 1967-only L78 396/375 hp on the launch-year 3963512 block is documented at the cowl-tag-level 1967 format (the 1967-only door-jamb trim tag schema) — distinct from the 1968-onward 3963512/carrier L78 chain.
L78 396/375 hp carryover (1969-only)
1969 · 1969-only L78 396/375 hp carryover on the 1969 Camaro
The 1969-only L78 396/375 hp carryover is a single-model-year continuation on the 1969 Camaro — documented at the cowl tag L78 RPO code on the 1969-year-specific Fisher cowl tag letter-pair codes. The 1969 L78 396/375 hp is distinct from the 1968 L78 on the 1968-onward cowl tag format. Reading a 1969 Camaro L78 against a 1968-onward L78 documentation reference reads as mis-documented at the year-specific discriminator.
L89 396/375 hp aluminum heads (1969-only)
1969 · 1969-only L89 396 aluminum-heads fitment on the 1969 Camaro
The 1969-only L89 396/375 hp aluminum-heads fitment is documented by FOUR L89-only hardware items: the L89-only aluminum cylinder heads (lighter than the L78 cast-iron oval-port heads), the L89-only rectangular-port LS6-spec head casting, the L78 ordering-code + L89 head-options pairing, and the 1969-only cowl tag L89 RPO code. The L89 was ordered in low volume — cross-check the cowl tag L89 RPO code against the build sheet, not against the engine-stamped block code alone.
L72 427-cubic-inch big-block (1969-only Camaro special)
1969 · 1969-only L72 427-cubic-inch big-block Camaro special (where fitted)
The 1969-only L72 427-cubic-inch big-block Camaro special is documented at the engine-stamped casting 3963512 L72 427 block code on the 1969 Camaro. The L72 427 block code is shared with the 1969 COPO Camaro ZL1 427 (the all-aluminum 427) at the cast-iron-block-vs-all-aluminum-block level — but the L72 cast-iron block code is distinct from the ZL1 all-aluminum 427. A 1969 L72-ordered Camaro with a ZL1 cowl tag TO-code reads as mis-restored at the block-spec level.
ZL1 all-aluminum 427 COPO 9561 (1969-only)
1969 · 1969-only ZL1 all-aluminum 427 Central Office Production Order 9561 fitment
The 1969-only ZL1 all-aluminum 427 COPO 9561 single-model-year fitment — 69 ZL1s built. Documented by FOUR ZL1-only hardware items: the ZL1-only all-aluminum 427 short block (lighter than the cast-iron L72 by approximately 100 lbs), the ZL1-only aluminum heads with the rectangular-port casting, the ZL1-only Holley 4150 list #4153 780-cfm carburetor, and the 1969-only COPO 9561 Central Office Production Order order code stamped on the cowl tag TO-code prefix. The ZL1 is a single-model-year fitment — cross-check the cowl tag TO-code prefix against the build sheet, not against the engine-stamped block code alone.
LS5 454 big-block (1970-onward)
1970-onward · 1970-onward SS 454 with the 1970 LS6 454 / 1971 LS5 454 chain
The 1970-onward LS5 454 big-block runs the 1970 LS6 454 (450 hp) / 1971 LS5 454 (360 hp) carryover / 1972 LS4 454 emissions-era reduced-output (310 hp) / 1973 LS4 454 (310 hp). The 1970 LS6 454 cast-iron short-block casting 3999289 is documented at the build-sheet level, distinct from the LS5 cast-iron intake and the LS4 emissions-era reduced-output calibration. Cross-check the LS6 / LS5 / LS4 RPO code against the build sheet, not against the engine-stamped block code alone.
LG4 305-cubic-inch (5.0 L) V8 (1982-onward)
1982-onward · 1982-onward third-gen standard V8 (carbureted)
Chevrolet-side LG4 305-cubic-inch (5.0 L) V8 debuts as the 1982-onward third-gen Camaro standard V8 (the carbureted base V8 for the 1982-onward third-gen chassis). The LG4 305 casting is distinct from any first-gen / second-gen Camaro small-block / big-block — Chevrolet-side only. Reading a third-gen Camaro with the LG4 RPO absent from the build sheet reads as mis-ordered at the base-engine level.
L98 350-cubic-inch (5.7 L) TPI V8 (1985-onward)
1985-onward · 1985-onward third-gen TPI (Tuned Port Injection) 350 V8 fuel-injection
Chevrolet-side L98 350-cubic-inch (5.7 L) TPI (Tuned Port Injection) V8 — the 1985-onward third-gen fuel-injection powertrain debut. The L98 TPI 350 is the 1985-onward IROC-Z race-prepped trim package powertrain layer, distinct from the 1982-onward carbureted LG4 305. The L98 TPI 350 fuel-injection calibration is documented at the cowl tag L98 RPO code.
LB9 5.7 L TPI V8 (1988-onward)
1988-onward · 1988-onward third-gen 5.7 L TPI V8 fuel-injection upgrade
Chevrolet-side LB9 5.7 L TPI V8 — the 1988-onward third-gen 5.7-liter fuel-injection upgrade on the third-gen Camaro, paired with the 1988-onward IROC-Z RPO Z6C layer where ordered. The LB9 5.7 L is distinct from the 1985-onward L98 TPI 350 — the 1988-onward LB9 5.7 L is a 5.7-liter fuel-injection calibration, distinct from the 1985-onward L98 TPI 350.
The Z-code (Z21 Z22 Z28 ZL1 Z6C Z65 Z7A Z11) and non-Z-code (D80 Hideaway Headlights / G80 Positraction) ordering-code discriminators on the 1967-onward through 1992-onward Camaro trim ladder — each on its own build-sheet ordering code path and year-specific trim-tag / cowl-tag discriminator.
Reading a 1969-only ZL1 cowl tag TO-code against a non-COPO 1969 Camaro reads as mis-documented at the assembly-plant level. A 1985-onward IROC-Z with the Z6C stripe without the L98 TPI 350 V8 fuel-injection pairing reads as mis-restored at the powertrain level. A 1967-only Z22 RS layer applied to a 1968-onward Camaro chassis reads as mis-formatted at the trim-tag level.
VIN / cowl-tag / trim-tag decoding
GM 13-digit VIN, the 1967-only door-jamb trim tag, and the 1991-onward WX3 / WX4 cowl-tag discriminator.
The Chevolet-side cowl tag, the trim tag, and the VIN — three distinct art surfaces that authenticate the 1967-onward through 1992-onward Camaro against the GM F-body 108-inch-wheelbase shared unibody chassis. NOT any Pontiac Firebird / Ford Mustang / Mercury Cougar / Olds 442 / Chevelle SS / Buick GS shared documentation reference.
GM 13-digit VIN
The Chevrolet Camaro VIN across the 1967-onward through 1992-onward production run carries the GM 13-digit format: positions 1-3 the GM manufacturer code (1 = Chevrolet), positions 4-5 the body series code, positions 6-7 the engine code (L30 = 327 base / L35 = 396 base / L78 = 396/375 hp / ZL1 = 1969-only aluminum 427 / LS6 = 1970 LS6 454 / LS5 = 1970-onward LS5 454 / LS4 = 1972-onward LS4 454 / LG4 = 1982-onward 305 / L98 = 1985-onward L98 TPI 350 / LB9 = 1988-onward 5.7 L TPI / WX3 / WX4 = 1991-onward cross-fire fuel-injection cowl-tag discriminator), positions 8 the restraint system / model-year code / assembly plant, positions 9 the check digit, positions 10 the model-year, positions 11 the assembly plant, positions 12-13 the sequential production number. The VIN is the manufacturer-level authentication chain — a Camaro chassis reading against a Pontiac Firebird / Mercury Cougar / Ford Mustang VIN-position format reads as mis-documented at the manufacturer level.
Cowl tag
The Camaro cowl tag (mounted on the cowl under the hood from 1968-onward, on the door-jamb from 1967-only) carries the year-specific discriminator: 1967-only door-jamb trim tag schema (NOT the 1968-onward Fisher cowl tag), the 1968-onward Fisher cowl tag standardization through the 1973-onward first-gen close, the 1974-onward second-gen cowl tag format change, and the 1982-onward third-gen cowl tag format change. The 1985-onward IROC-Z RPO Z6C ordering code is stamped on the cowl tag (NOT the trim tag) where the chassis was ordered with the IROC-Z layer. The 1991–1992-onward WX3 / WX4 cross-fire fuel-injection cowl-tag discriminator layers the WX3 / WX4 RPO codes onto the cowl tag to authenticate the cross-fire fuel-injection calibration.
Trim tag
The Camaro trim tag (F-body-side format, distinct from the GM A-body Chevelle trim-tag format) carries the year-specific discriminator: the 1967-only door-jamb trim tag schema (a Fisher body code stamped on the door-jamb-mounted identification plate), the 1968-onward first-gen trim-tag format (the 1968-onward Fisher Body cowl tag layout), the 1974-onward second-gen trim-tag format change at the second-gen rollover, and the 1982-onward third-gen trim-tag format change at the third-gen rollover. The 1967-onward X77 trim-tag discriminator authenticates an SS-equipped Camaro at the trim-tag level (the X77 tag is on the trim tag, NOT the cowl tag). Cross-check the trim tag against the cowl tag AND the VIN — a Camaro chassis with a mismatched trim-tag format reads as mis-documented at the trim-tag discriminator level.
Transmission + rear-end matrix
Turbo Hydra-Matic TH-350 / TH-400 / 700R4 standard + Muncie 4-speed + Borg-Warner T-5 5-speed + GM 12-bolt / 8.875-inch / 8.5-inch rear axle.
Transmission
The Camaro transmission lineup spans the 1967-onward Turbo Hydra-Matic TH-350 / TH-400 standard fitment on the first-gen, the 1967-onward Muncie 4-speed manual on the Z/28 / SS 396 fitments, the 1970-onward Muncie 4-speed manual carryover on the second-gen, the 1982-onward Borg-Warner T-5 5-speed manual on the third-gen, the 1982-onward Turbo Hydra-Matic 700R4 automatic, the 1985-onward Turbo Hydra-Matic 700R4 on the IROC-Z RPO Z6C layer, and the 1991-onward TH-700R4 / 4L60 automatic carryover. A first-gen Z/28 Camaro chassis with a Chevrolet Turbo Hydra-Matic stamp reads as standard — but a Z/28 with a Muncie 4-speed stamped on the Z/28-only block reads as the build-sheet-ordered Z/28 with the 4-speed. The Muncie 4-speed stamp is documented at the build-sheet level on the 1967-onward camaro Z/28 fitment.
Rear axle
The Camaro rear axle lineup spans the 1967-onward GM 12-bolt rear axle (first-gen), the 1970-onward GM 8.875-inch 10-bolt rear axle (second-gen), and the 1982-onward GM 8.5-inch 10-bolt rear axle (third-gen). The 1967-onward Positraction rear (RPO G80) is standard on the Z/28 — an open-differential Z/28 reads as mis-restored at the differential level. The 1970-onward Limited-Slip differential option on the SS 396 fitment carries the G80 RPO code on the build sheet. The 1982-onward Camaro Z/28 third-gen carries the 8.5-inch 10-bolt rear axle as standard, with the G80 Positraction optional. The rear-axle build tag (Chevrolet-side format on the F-body 108-inch-wheelbase chassis) records the exact ratio + the limited-slip presence vs the standard open-differential. A 1967-onward Z/28 chassis with a non-G80 documentation reference reads as mis-documented at the rear-axle level.
Numbers-matching pointers
The four-step authentication chain — deepest link forward to the marque-anchor provenance block.
Cowl tag Z-code ↔ DZ 302 small-block casting 3892657 K-suffix
The 1967-onward Z/28 authentication chain runs through the cowl tag Z-code (the Z- prefix ordering code authenticating the Z/28 fitment) and the DZ-coded 302 small-block (casting 3892657 with K-suffix date-code stamp). A Camaro chassis with an X77 cowl tag is an SS 396 Camaro — NOT a Z/28. A Camaro chassis with a Z cowl tag and an X77 engine stamped on the block is the off-by-one-fitment error on the F-body Camaro track. Cross-check the cowl tag Z-code against the DZ 302 casting 3892657 K-suffix stamp, NOT against the fender badge.
Open the provenance block →1969-only ZL1 cowl tag TO-code prefix ↔ all-aluminum 427 (COPO 9561)
The 1969-only ZL1 all-aluminum 427 COPO 9561 single-model-year fitment is documented at the cowl tag TO-code prefix (the TO-code prefix authenticating a COPO-order 9561 build, NOT the engine-stamped L72 427 block code alone). The L72 427 block code is shared with the 1969-onward COPO / non-COPO Camaro fitments at the cast-iron-block-vs-all-aluminum-block level. Reading a 1969 Camaro with the ZL1 cowl tag TO-code prefix is the engineering authentication chain; reading a 1969 ZL1 chassis against the engine-stamped cast-iron L72 427 block code alone reads as mis-documented at the block-spec level. Cross-check the TO-code prefix against the build sheet, NOT against the engine-stamped block code alone.
Open the provenance block →1985-onward IROC-Z RPO Z6C ↔ L98 TPI 350 V8 fuel-injection cowl tag
The 1985-onward IROC-Z RPO Z6C race-prepped trim package is documented at the build-sheet RPO Z6C ordering code and the L98 TPI 350 V8 fuel-injection powertrain pairing on the cowl tag. The IROC-Z is a TRIM package, NOT a separate model line — it pairs the Z6C ordering code with the L98 TPI 350 fuel-injected powertrain. A third-gen Camaro chassis with the IROC-Z decals cosmetically applied (the Z6C-specific 16-inch alloy wheels + Z6C-specific front / rear spoilers + Z6C-specific decals NOT present) reads as mis-restored at the trim-package level; the RPO Z6C build-sheet ordering code is the discriminator.
Open the provenance block →1967-only door-jamb trim tag ↔ 1968-onward Fisher cowl tag discriminator
The 1967 Camaro shipped with a door-jamb-mounted identification plate (door-jamb trim tag) — distinct from the 1968-onward Fisher cowl tag stamped on the cowl under the hood. The 1967-only door-jamb trim tag schema carries the Fisher body code, body style code, paint code, trim code, build plant, and Year-Plus-Week sequence at the door jamb. The 1968-onward Fisher cowl tag standardizes the same fields on the cowl under the hood. A 1967 Camaro chassis reading against a 1968-onward Fisher cowl tag reads as mis-documented at the trim-tag format level. Cross-check the trim tag location AND format against the year-specific discriminator.

What fails the judging lane — three Camaro restoration pitfalls.
1967-only door-jamb trim tag schema vs 1968-onward Fisher cowl tag
A 1967 Camaro chassis with the 1968-onward Fisher cowl tag reads as mis-documented at the trim-tag format level. A 1968-onward Camaro chassis with the 1967-only door-jamb trim tag schema reads as mis-formatted at the trim-tag format level. Restoration must verify the trim tag location AND format against the year-specific discriminator (1967-only door-jamb trim tag schema vs 1968-onward Fisher cowl tag).
1969 ZL1 cowl tag TO-code prefix mis-applied to non-COPO 1969 Camaro
The 1969-only ZL1 cowl tag TO-code prefix authenticates the COPO 9561 single-model-year fitment. A 1969 Camaro chassis WITHOUT the ZL1 cowl tag TO-code prefix cannot be authenticated as a ZL1 fitment at the cowl-tag level — even with the all-aluminum 427 short block swapped in, the ZL1 must authenticate at the cowl tag TO-code prefix AND the build sheet ordering code. Restoration must verify the cowl tag TO-code prefix against the build sheet, NOT against the engine-stamped block code alone.
1985-onward IROC-Z RPO Z6C ordered car with non-spec L98 TPI 350 V8
A third-gen Camaro chassis with the 1985-onward IROC-Z RPO Z6C race-prepped trim package must pair the Z6C ordering code with the 1985-onward L98 TPI 350 V8 fuel-injection powertrain. A third-gen Camaro with the IROC-Z Z6C ordering code WITHOUT the L98 TPI 350 V8 (carbureted LG4 305 instead) reads as mis-restored at the powertrain level. Restoration must verify the L98 TPI 350 V8 fuel-injection against the Z6C ordering code on the build sheet.

The broader Chevrolet restoration guide family covers the Camaro first-gen F-body era-bundle, the Z/28 marque-stub, the Corvette C2 / C3 companion guide, the 1969 Camaro frame-off multi-guide bundle, the Impala 1958 era-bundle, and the 1964 Chevelle per-year compeer — six cross-links covering the year-by-year ecosystem underneath the all-generations leaf.
The first-gen-only era-bundle — the 1967 launch-year L30 327 / L35 396 / L78 396 progression, the 1968-onward Z/28 DZ 302, the 1969-only ZL1 all-aluminum 427 COPO 9561, the 1970-onward LS6 454 / LS5 454 / LS4 454 SS option chain, and the 1967-only door-jamb trim tag vs the 1968-onward Fisher cowl tag.
The Z/28-specific marque-stub preview — the Z-code stamped-cowl-tag authentication, the DZ 302 small-block (casting 3892657 K-suffix), the Z21 stripe option code, the 1969 Z/28-only aluminum intake manifold, the 1969 D80 Hideaway Headlights (1969-only Z/28 option), and the 1967-onward G80 Positraction standard.
The companion C2/C3 Corvette companion guide — the 1963-onward stub-frame chassis fitment, the 1967-onward L88 aluminum 427 RPO option (216 L88s built across 1967 / 1968 / 1969), the C3 Corvette stub-frame documentation track, and the F-body-vs-C3 marque-cross reference.

The 1958-era Chevrolet Impala companion — the 1958 launch-year B-body Impala (the 1958-onward fourth-generation B-body 117.5-inch-wheelbase unibody), distinct from the F-body Camaro unibody and the A-body Chevelle unibody.
The 1964 Chevrolet Chevelle companion — the 1964-onward A-body 112-inch-wheelbase Chevelle unibody, distinct from the F-body Camaro 108-inch-wheelbase unibody. The A-body cross-marque-discriminator is the cowl tag car-line code, NOT the engine-stamped block code.
Restoration difficulty
The Chevrolet Camaro is a Specialist-grade restoration. Here is why.
- 1. The Chevrolet Camaro sits on the GM F-body 108-inch-wheelbase unibody shared with the Pontiac Firebird / Mercury Cougar / Ford Mustang re-bodged Mustang II — the F-body Camaro cowl tag vs the F-body Firebird cowl tag vs the Mustang II cowl tag differ at the body-code level. A Camaro chassis with a Pontiac Firebird / F-body-shared Firebird cowl tag reads as mis-documented at the body-code level.
- 2. Engine progression across 12 distinct Chevrolet-side displacement families at five castings (302 DZ Z/28 / 327 L30 / 350 LU / LS-series 396 L35 L34 L78 / 396 L78 (1969-only L78 carryover) / 396 L89 (1969-only aluminum heads) / 427 L72 (1969-only Camaro special) / 427 ZL1 COPO (1969-only all-aluminum) / 454 LS5 (1970-onward LS6/LS5/LS4) / 305 LG4 (1982-onward) / 350 L98 TPI (1985-onward) / 5.7 L LB9 TPI (1988-onward)) — each cylinder head bolt-pattern + balancer pattern + cast-iron block casting distinct from any Pontiac / Olds / Buick marque-cross engine. Cross-marque swaps mis-restore at the engine level.
- 3. Six Z-code (Z21 Z22 Z28 ZL1 Z6C Z65 Z7A) / three non-Z-code (D80 Hideaway Headlights / G80 Positraction / Z11 drag pak) RPO codes interleave on the 1967-onward through 1992-onward Camaro trim ladder — the 1967-only Z22 RS one-year window, the 1969-only ZL1 COPO 9561 fitment, the 1985-onward IROC-Z RPO Z6C layer, the 1991-onward WX3 / WX4 cross-fire fuel-injection cowl-tag discriminator. Cross-references between the Z-code ordering codes require build-sheet verification against the trim-tag format + cowl-tag format + VIN positions.
- 4. The 1967-only door-jamb trim tag schema vs the 1968-onward Fisher cowl tag is a year-specific discriminator that authenticates against the trim tag location AND format — NOT against the chassis year alone. A 1967 Camaro with a 1968-onward Fisher cowl tag reads as mis-documented at the trim-tag format level; a 1968-onward Camaro with the 1967-only door-jamb trim tag schema reads as mis-formatted. Restoration must verify the trim tag location separately from the year-specific discriminator.
- 5. The Camaro provenance chain runs through the cowl tag Z-code ↔ DZ 302 small-block castings 3892657 K-suffix ↔ X77 trim-tag discriminator (1967-onward SS 396 paths) ↔ 1969-only ZL1 cowl tag TO-code prefix ↔ 1970 split-year Z/28 DZ 302 carryover (NOT the 1970-onward second-gen) ↔ 1985-onward IROC-Z RPO Z6C trim package ordering code ↔ L98 TPI 350 V8 fuel-injection pairing ↔ 1991-onward WX3 / WX4 cross-fire fuel-injection cowl-tag discriminator. Without a complete Chevrolet-side provenance chain, a numbers-matching claim degrades into a tribute — and a Camaro chassis reading against a Pontiac Firebird / Ford Mustang II / Mercury Cougar cross-marque body-code documentation reference reads as mis-restored at the marque level.
