The Ford FE engine is a Ford V8 engine used in vehicles sold in the North American market between 1958 and 1976. A related engine, the Ford FT engine, was used in medium and heavy trucks from 1964 through 1978. The FE filled the need for a medium-displacement engine created by the discontinuation of the Lincoln Y-block V8 engine. The FE joined Ford's other V8s which included a small Y-block and the big block MEL engines. "FE" is an acronym for 'Ford-Edsel'. Versions designed for use in trucks and school buses were known as "FT", an acronym for 'Ford-Truck', and differed primarily by having steel (instead of nodular iron) crankshafts, larger crank snouts and different distributors.
