Accufab’s Cylinder Head Block Dowels, (set of 4) are designed for the Ford Modular Motor and fits 4.6L, 5.4L, 5.8L 2V and 4V as well as Coyote engines.
Accufab has built many record setting and race winning engines through the years. During this time, we’ve developed parts that are useful to us for our own engine building needs.
The dowels are made from heat treated steel and threaded on the inside for easier removal, plus they are reusable!
Mod Motor Trivia: The Ford Modular engine is Ford Motor Company’s overhead camshaft (OHC) V8 and V10 gasoline-powered small block engine family. The Modular engine got its name from its design and sharing of certain parts among the engine family, starting with the 4.6L in 1990 for the 1991 model year. The name was also 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 then additional capacity was added in Windsor, Ontario.
The 5.0 L; 302.1 cu in (4,951 cc) “Coyote” V8 is the latest evolution of the Modular engine. Ford engineers needed to design a V8, specifically for the Mustang GT, that would compete with the GM 6.2L LS3 used in the new Chevrolet Camaro, and the new Chrysler 6.4L Hemi ESF in the Charger, Challenger, and Grand Cherokee. This engine had to remain close to the same physical size of the outgoing 4.6, and share other specifications with it such as bore spacing, deck height, bell housing bolt pattern, etc. in order for the engine to utilize existing Modular production line tooling (the source of the ‘Modular’ designation for the engine family).
