The Ford 4.6L engine is a naturally aspirated V8 from Ford Motor used to power a variety of different vehicles like sports cars, pickup trucks, sport utility vehicles, luxury sedans and cargo vans. Throughout its lifespan, it was offered with either 2, 3 or 4 valves per cylinder, featured either a single (SOHC) or a dual overhead cam (DOHC) setup. Built between 1990 and 2014, the Ford 4.6L architecture was one of the first engines to be part of the Ford Modular family.

The first vehicle to be powered by this engine was the Lincoln Town Car in 1990. Back then, its 2-valve SOHC configuration allowed to developed 190 horsepower and 260 lb-ft of torque. However, by the end of its lifespan, modern technology like dual overhead camshafts and forced induction enabled this engine to produce much more power. The most powerful iteration of this engine in a FoMoCo production vehicle was the supercharged V8 – codenamed Terminator – which powered the 2003-2004 Ford Mustang SVT Cobra. In that application, the 4.6L V8 produced 390 horsepower and 390 pound-feet of torque.
Interestingly, a heavily modified version of Ford’s modular 4.6L V8 was used to propel the Swedish-built, Koenigsegg CCR V8 supercar. That application saw an increase in displaced to 4.7L as well as the use of two centrifugal superchargers – rather than a single twin-scroll unit used by Ford – to reach a staggering output of 806 horsepower and 679 pound-feet.
