Good luck.

Well if you're a non 5.4L 3Valve owner, like myself, the 4.6L 2Valve V8 is shared between the Mustangs. After a few hours of research, the only thing I found different between our 4.6L V8s and the ones in the Mustang, is our compression, and a different cam. So essentially we can buy 4.6L V8 Mustang parts for our motors.
