Ford Modular engine

The Ford Modular engine is Ford Motor Company's overhead camshaft (OHC) V8 and V10 gasoline powered engine family. Contrary to popular belief, the Modular engine did not get its name from its design or sharing of certain parts among the engine family. Instead, the name was derived from a manufacturing plant protocol, "Modular", where the plant and its tooling could be changed in a few hours to manufacture different versions of the engine family. 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 for vehicles equipped with DOHC versions of the engines. The engines were first produced in Romeo, Michigan but additional capacity was added in Windsor, Canada.

4.6 L

The 4.6 L (4601 cc, 281 CID) 90-degree V8 has been offered in 2-valve SOHC, 3-valve SOHC, and 4-valve DOHC versions. The engines were also offered with both aluminum and cast iron blocks, depending on application. The 4.6 L's bore and stroke are nearly square at 90.2 mm (3.552 in) and 90 mm (3.543 in), respectively. Deck height for the 4.6 block is 227 mm (8.937 in) and connecting rod length is 150.7 mm (5.933 in) center to center, giving the 4.6 L a 1.67:1 rod to stroke ratio. Cylinder bore spacing measures 100 mm (3.937 in), which is common to all members of the Modular engine family. All Modular V8s, save for the new 5.0 L Coyote, utilize the same firing order as the Ford 5.0 L HO and 351 CID V8s (1-3-7-2-6-5-4-8). The 4.6 L engines have been assembled at Romeo Engine Plant, located in Romeo, MI, and at Windsor Engine Plant and Essex Engine Plant, both located in Windsor, Ontario.
