Spec & history — the 1973 Ford Mustang
The 1973-onward muscle-peak run-out + 8.5:1 + EGR / TAV / catalytic readiness.
The 1973 Ford Mustang is the 1973-onward final-year muscle-peak run-out on the conventional-frame 108-inch Ford pony-car chassis launched in 1964½ - this is the LAST model year before the 1974-onward Mustang II subcompact 94-inch body-on-frame replacement opens after the 1973 closure. The 1973-onward 8.5:1 emissions-era compression floor carries forward on the 302 / 351 Cleveland chain with the EGR / thermostatic-air-cleaner / catalytic converter readiness chain.
The 1973-only first-year Medium Bright Yellow launch color (Ford code 6, a.k.a. Chrome Yellow) anchors the final-year paint chip against the 1972-onward color carryover. The 1973-onward final-year discriminator on the door data plate line 1 model-year prefix chain pins the year-cross-check. The 1973-onward redesigned grille + chrome bumper with 5-mile bumper extension carryover to the 1974-onward Mustang II is the documented 1973-onward bumper-and-grille cross-check.
Concourse deep-dive — the 1973 Ford Mustang
Judging rubric, factory-correct finish, casting walk.
A 1973 Ford Mustang is judged on the 1973-onward muscle-peak run-out final-year on the 108-inch pony-car chassis, the 1973-onward 8.5:1 emissions-era compression floor (NOT a 1972-onward 10.0:1 / 11.0:1 Boss compression ratio), the 1973-onward EGR / TAV / catalytic converter readiness chain, the 1973-only first-year Medium Bright Yellow (Ford code 6), and the 1973-onward redesigned grille + chrome bumper with 5-mile bumper carryover.
Engine casting walk on the 1973 drivetrains: the 1973-onward 302 carries at 8.5:1 compression (the 1972-onward emissions-era closure floor) with the 1973-onward EGR / TAV readiness chain; the 1973-onward 351 Cleveland carries at 8.5:1 compression. A 1973 chassis missing the 1973-onward emissions-era readiness chain reads as mis-restored at the emissions-cross-check.
