The Ford Modular engine is an overhead camshaft (OHC) V8 and V10 gasoline-powered small block engine family introduced by Ford Motor Company in 1990 for the 1991 model year. The term “modular” applied to the setup of tooling and casting stations in the Windsor and Romeo engine manufacturing plants, not the engine itself.
The Modular engine family started with the 4.6 L in 1990 for the 1991 model year. The Modular engines are used in various Ford, Lincoln, and Mercury vehicles. Modular engines used in Ford trucks were marketed under the Triton name from 1997–2010 while the InTech name was used for a time at Lincoln and Mercury for vehicles equipped with DOHC versions of the engines. The engines were first produced at the Ford Romeo Engine Plant, then additional capacity was added at the Windsor Engine Plant in Windsor, Ontario.
