The Ford 4.6L and 5.4L 2V engines were a part of Ford's modular family of engines. The first modular engine appeared on the 1991 Lincoln Town Car. The engine has been a feature of various Ford vehicles such as the Mustang, Expedition, Crown Victoria, and F-series pickup trucks. The modular engines have a wide overhead cam that must accommodate eight or ten cylinders, but the engines also have a relatively small displacement. Both engines have a single overhead camshaft (SOHC).
