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.

In 1979-80, a draw-through, nonintercooled turbo version was produced for Mustang Cobras and some Capris. Lack of dealership and owner training resulted in many stuck turbochargers and other maintenance problems. They were limited to 5 PSI of boost, though Ford Motorsport sold a wastegate with an adjustable rod which allowed an increase up to 9 PSI. It was used in this carbureted form in a number of passenger cars, from the Fairmont Futura Turbo to the 1979 Indy Pace Car edition Mustang.
