Ford 351 Windsor

Ford 5.8L Specs & History

 

 

 

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 iteself was introduced in 1969, and earned a reputation for its strength, reliabiity, and durability. The engine's cylinder heads were designed to deliver broad torque production, comprimising 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.
