Ford 351 (5.8L) Windsor V-8

351W, 5.8L V-8 Engine Specs, History, & Info

The Ford Windsor engine (offered in several displacements) is considered one of the most successful Ford small blocks every produced. The Windsor engine family, amply named after the Windsor Engine Plant in Windsor, Ohio where they were originally manufactured, were introduced in 1962. The 351W itself was introduced in 1969, and earned a positive reputation for its strength, reliability, and durability. The engine's cylinder heads were designed to deliver a broad torque curve, compromising high rpm horsepower. Electronic fuel injection replaced carburetion for the 351W in 1988. The 351 Windsor was available in the Ford F-150 up to 1997, when it was replaced by the Ford Modular V-8. The engine has an identical 4.00" cylinder bore as the 302 cid V-8, but with a longer 3.50" stroke.
