This is my 99', it DID have a 4.6l, with E-303 cams, borla exhaust, superchips programmer, full borla exhuast, bigger injectors.. it made 317 at the wheels... Shelby Wheels, nitto 555 tires.. now, its gonna have a 2v 5.4 in it, hopefully with cams and a intake, and borla exhaust.. some bigger injectors as well..sctrictly performance is going to do the tune
