This Ford Shelby GT500 supercharged 5.4-liter, 32-valve V-8 evolves from Ford’s experience with tuning its modular, or MOD, engines. Output is a brawny 475 horsepower. Odometer reads very low miles at 7,713. The engine is force-fed an air-and-fuel mixture via a “Roots-type” supercharger providing 8.5 pounds per square inch of boost. The GT500 uses a cast-iron engine block. It borrows from the Ford GT program aluminum, four-valve cylinder heads, piston rings and bearings, adding a high level of performance durability to the drivetrain. “Powered by SVT” camshaft covers add the finishing touch to the engine. Helping put the power to the pavement is a 6-speed manual gearbox. For the performance driver, its evenly spaced gears mean less “stirring” is needed to find the “sweet spot.”Â
