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 I4 DOHC engine
The engine was originally designed to replace the 2.0 L OHC Pinto engine, derivatives of which had powered most of Ford's four-cylinder rear-wheel drive cars since the early 1970s, and which was by that time lagging behind the competition in terms of power output, efficiency and refinement. Equipped with a newly designed twin-cam cylinder head but still only 8 valves, and a "square" 86x86mm bore and stroke, the new I4 was launched in the Ford Sierra and Scorpio, mated to either the also new all-synchromesh MT-75 5-speed manual transmission or the existing A4LD four-speed automatic. The engine received mixed reviews, being seen as an improvement over the Pinto, but not the leap forward one might have expected.
