This engine started out its life as a great 302 ci engine, not so after it was de-tuned and modified, it was really sick after the Ford modifications. After modifications, it ended up being a 255 ci engine. Fortunately for mankind, the engine only saw two years of service and was retired. Thank God the 302ci (5.0L) was brought back in 1982. Following the second oil crisis in 1979, the 302 cu in (4.9 L) “5.0” engine was dropped in favor of a new 255 cu in (4.2 L) V8 due to its better fuel economy.
