Think about it.... This 5.3L came out of an 07/08 Tahoe the stock numbers are ( For SUV applications, it is rated at 320 hp (239 kW) and 340 ft•lbf (461 N•m) of torque)... If you don't think this engine will pick up 80hp with a set of 220cc ported heads flowing 288@.600L, a much larger cam (for a 5.3L), ported intake and ported TB... ? Like I said 400+. It will all come down to the tune, I would recommend bigger injectors as well but my 04 ran fine with the injectors at 27#.... Heck I can throw a set of long tubes on that stock 5.3L and get 340hp..lol (now all ya need is 40hp to hit 400) I understand your thoughts but I have found these little 5.3L will get it!
The HP on my 04 was calculated based on Trap speed and weight (the best way to get real hp #'s) 1/4 time: 13.42 / Trap speed: 107.5 / Weight 4680 with me in it and the tonu (spelling?) cover. =418.24BHP
damn i never thought of it that way those are some damn good numbers!!! will an ls6 cam work better than the ls2 cam with that setup?
