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 Pinto
The design of the Pinto fuel system was complicated by the uncertain regulatory environment during the development period. The first federal standard for automotive fuel system safety, passed in 1967, known as Section 301 in the Federal Motor Vehicle Safety Standards, initially only considered front impacts. In January 1969, 18 months into the Pinto's development cycle, the NHTSA proposed expanding the standard to cover rear-end collisions. The proposed standard was based on a 20 mph moving-barrier rear impact test. Ford publicly announced it supported the standard. In August 1970, the month the Pinto went into production, the NHTSA changed the proposal to a more stringent 20 mph fixed-barrier standard which car companies were to meet in 18 months. The fixed-barrier standard was seen by the auto industry as a significant increase in test severity. At the same time the NHTSA announced a long-term goal of setting a 30-mph fixed-barrier standard. Due to the confusion related to the various proposed standards and an expectation that the NHTSA would not select the more stringent 30 mph fixed-barrier standard, Ford elected to voluntarily meet the 20 mph moving-barrier standard for all cars by 1973. Ford and other automobile manufacturers objected to the more stringent fuel system safety standard and filed objections during the required comment periods of the proposed regulations.
