The Y-block engine is a family of overhead valve V8 automobile piston engines from Ford Motor Company. It was introduced in 1954 (1953 trucks celebrated 50 years of Ford with a flathead V8) on Ford trucks and cars to replace the side-valved Ford flathead engine and was replaced by the Ford FE engine (on medium cars) and the Ford Windsor engine (on small cars) in 1962, and lasted until 1964 in Ford trucks.
Lincoln introduced a very different and larger Y-block engine in 1952 for use on large cars and on Ford heavy duty trucks.
