Ford announces production of the 10 millionth V-8 engine produced at its ROMEO plant in Michigan. It will be installed - in 4.6-liter, three-valve-per-cylinder variety - in a 2010 Mustang produced at the automaker's Flat Rock, Michigan assembly plant. Romeo Engine Plant produces V-8 engines at the rate of 140 per hour for the Mustang, Shelby GT500, Ford F-150, Explorer, E-Series van, Crown Victoria (now only a fleet vehicle), Lincoln Town Car, and the Mercury Grand Marquis.

The V-8 is of an overhead camshaft design that was unusual for a domestically-produced V-8 when it was introduced in the 1991 Lincoln Town Car; previous Ford, GM, and Chrysler V-8s used a simpler and cheaper in-block camshaft design that resulted in more friction (and thus less efficient operation).
The engine has been produced primarily in two displacements - 4.6-liter, 5.4-liter - and is most notable for powering iconic products like the Ford Mustang (including the new 2010 Mustang) and the F-series trucks. It has used two-valve, three-valve, and four-valve-per-cylinder head designs, and has been supercharged for use in Ford's GT supercar.
