The Ford "Windsor" engine is a series of automobile V8 engines built by the Ford Motor Company beginning in July 1961. The engine was discontinued in new vehicles in 2001, but remains available for purchase from Ford Racing and Performance Parts as a crate engine. The "Windsor" designation is a retroactive name for the family of engines sharing a common basic engine block design. Ford adopted the designation specifically to distinguish the 351 cu in (5.8 L) displacement version from the "Cleveland" 335-family engine of the same displacement.
