Spec & history — the 1968 Chevelle SS 396
The 1968-onward Fisher Body cowl tag + 396 / 427 chain.
The 1968 Chevrolet Chevelle SS 396 carries the 1968-onward Mark IV 396 cubic-inch V8 family and the 1968-onward L72 427 cubic-inch refresh chain on the 1964-onward A-body 112-inch-wheelbase chassis. The 1968-onward Fisher Body cowl tag standardization arrives at the 1968-onward model year — the 1964-1967-only door-jamb trim tag format retires to the 1968-onward Fisher Body cowl tag layout mounted on the driver-side upper cowl. A 1968 Chevelle chassis with a 1964-1967-only door-jamb trim tag stamped format reads as mis-format-decoded at the trim-tag-format level.
The 1968-onward Mark IV 396 block casting 3963512-D (the 1968-onward 396 chain carryover) is paired with the 1968-onward L34 / L78 closed-chamber 781 cylinder heads and the 1968-onward L72 carryover closed-chamber 781 head pattern. The 1968-onward cast-iron intake 3965589 carries forward. The 1968-onward L72 427 carries the 4.250-inch bore at 3.760-inch stroke, closed-chamber 781 heads, and the 1968-onward 4150 Holley 780 cfm 4-barrel.

Judging rubric, factory-correct finish, casting walk.
A 1968 Chevelle SS 396 is judged on the 1968-onward Fisher Body cowl tag standardization (the 1968-onward cowl tag mounted on the driver-side upper cowl, NOT the 1964-1967-only door-jamb trim tag format), the 1968-onward L34 / L78 / L89 RPO codes on the build sheet, the 1968-onward Mark IV 396 closed-chamber 781 heads, and the 1968-onward ZL2 Cowl Induction stamping verification.
Factory-correct finish on the 1968 Chevelle SS 396 is single-stage acrylic lacquer, NOT the post-1970 BC/CC. The 1968-onward lacquer lay-down was run at the 1968-onward final assembly plant. The 1968-onward SS 396 dual fan-stripe layout carries forward from the 1967-onward SS 396 graphic into the 1968-onward Super Sport stripe cycle.
