Because of a strong enthusiast response to the introduction of the 2003 Mustang Mach 1, Ford committed to another sales year of Mach 1 production to slot between the Mustang GT and the SVT Mustang Cobra. Since the Mach 1 was a performance model above the GT, it’s 4.6-liter V8 engine featured some enhancements, including high-flow cylinder heads, special cams and a sporty exhaust. These changes enable the mill to produce 305 hp and 320 lb/ft of torque. It was available as either and automatic or manual transmission.
