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.
Ford Torino
The Federal Clean Air Act caused Ford to install catalytic converters for 1975 to help meet new emission standards. The converter significantly reduced the power output of the engines due to increased exhaust back pressure. In response, Ford revised the base engine on all Torinos to the 351-2V engine. Along with this change, the Cruise-O-Matic transmission became standard; no manual transmissions were available. Power for all engines, except the 460, was significantly reduced compared to 1974, and with the weight increase, fuel economy and performance continued to decrease. The 400-2V and the 460-4V were the only engine options, as the 351-4V was no longer available.
