The 5,409 cc (5.4 L; 330.1 cubic inch) V8 is a member of the Modular engine family first introduced in the 1997 F-series pickups, in place of the 5.8L 351W. In 1999, Ford introduced the DOHC 4-valve 5.4 L in the Lincoln Navigator. Ford later used versions of the DOHC 4-valve 5.4 L in the 2000 Ford Mustang SVT Cobra R, the Ford GT supercar, and the Ford Shelby GT500. The Shelby GT500 uses a 4-valve DOHC 5.4 L with an Eaton M122H Roots type supercharger and air-to-liquid intercooler. The GT500 5.4 L shares its high-flow cylinder head castings with the Ford GT, with only minor machining differences, and shares camshafts with the 2003–2004 Ford Mustang SVT Cobra.
