 The Cobra used a 4.6 DOHC V8 as well, however it was a cast-iron block with forged internals and a supercharger, they are commonly mistaken to have the same block.It was conservatively rated at 305 hp (310 hp in 2004).Other special features included "retro" interior styling, with seats made to look like the "comfortweave" seats in the original Mach 1s, old-style gauges, and aluminum pedals and shifter.
