i dont believe your car launches better with irs thats bull you have wheel hop out the *** thats what plagues irs and you cant overcome it without spending loads of money. and people switch to a solid rear cause because of the wheel hop and the fact that if you run slicks with a stock cobra at the track you will probably blow it up

 

okay sweet so the verdict is basically to go with a pro and basically popping a new engine in... so question then will the 5.4 Triton be an easy replacement?

 

Pretty much the same. Just need custom tuning to make it run right.
