Ford Mustang
Engines for the 1974 models included the venerable 2.3 L I-4 from the Pinto and the 2.8 L Cologne V6 from the Mercury Capri. The 1975 model year reintroduced Windsor V8 that was only available with the C-4 automatic transmission, power brakes, and power steering. This continued through production end in 1978. Other transmissions were the RAD 4-speed with unique gearing for all three engines, and the C-3 automatic behind the 2.3 L and 2.8 L. The 5.0 L designation was not applied until the 1978 King Cobra model. All 302 equipped Mustang II's, except the King Cobra received an updated version of the classic Ford "V8" emblem on each front fender.
Pontiac Fiero
All automatic-equipped Fieros were equipped with the three-speed Turbo-Hydramatic 125 with torque converter lockup.
Automatic transmission final drive ratios:All four-speed manual transmissions were built at the Muncie, Indiana Allison plant. The 1984 production line saw two transmissions, a performance four-speed with a final drive ratio of 4.10, and an economy four-speed with a final drive ratio of 3.32. The V6 on the 1985 model and part of the 1986 production year came with a four-speed with a final drive ratio of 3.65. The lower-geared 4.10 four-speed transmission showed improved acceleration, but sacrificed fuel economy.
