Ford 4.6L 2/3/4-valve V8 Engine: Specs, Problems, and Reliability. The Ford 4.6 L V8 engine, the first member of Ford's Modular overhead camshaft engine family in the production, was presented in the 1991 Lincoln Town Car. It was a 4.6-liter 90-degree V-angle eight-cylinder gasoline engine with two valves per cylinder and SOHC design. Later, this engine became the base V8 in the Mustang GT. Ford also has been produced a 4-valve DOHC version popular by SVT Cobra and Mach 1 applications. This 32-valve DOHC 4.6 L engine debuted in the 1993 Lincoln Mark VIII under name of 4.6 L Four-Cam V8. The new Modular 4.6-liter V8 series replaced its pushrod-based predecessor - Ford's Small Block 5.0 H.O. engine.

Ford's 4.6 L V8 has a deep-skirt aluminum or cast iron cylinder block (Romeo and Windsor castings), depending on model year and application. While Windsor iron blocks have "W" letter and dowel pins at the cross-bolted main caps, Romeo 4.6 iron blocks have jackscrew cross-bolted main caps and are identified by "R" (but not every one of them). Otherwise, they look the same. Aluminum cylinder blocks were cast at the Windsor Aluminum Plant (WAP) by the exception of older 90s Teksid blocks, which were cast in Turin, Italy. Aluminum blocks came with 6-bolt main bearing caps.
