Check mine out. My site I just got it "done" (Never really done). I rebuilt a 235 with a little cam in it. Sounds cool and I don't even have dual exhaust yet. I went with a T5 5speed and a 3.73 rear end. 5th gear is a little to tall. (have to be on flat road with no hills) I could have used a 4.11 rear no problem. Let me know if you have any questions. I'd be happy to help. Good luck
