<div class='quotetop'>QUOTE (distant00 @ Dec 12 2007, 03:09 PM) </div>there not worth doing if thats all your putting on the engine.
but
if you have some cams and a set of extractors to suit, with after market management, then you get good gains.
I got gains on a standard motor. But yer, obviously your going to get a lot more from Cams, Headers, Exhaust, Ecu in the full blow.
how much do u guys think i will gain, bigport bottom end (stock), smallport head, fully ported and polished, t3 manifold, ST quads, t3 trumpets (75mm), HKS valve springs, Wade 308 duration cams, t3 adjustable cam gears, adaptronic computer, n hopefully a fkn mad tune

<div class='quotetop'>QUOTE (drftr86 @ Dec 14 2007, 10:34 PM) </div>i have most of that except 288 cams and an safc piggy back and im making 81rwkw.
a tunable ecu will give it a little more.
i wouldn't use a stock bottom end with 308 cams. your top power range would be around 9000rpm.
also youd want some half decent extractors.
yeh i realise that bottom end wont hold up revs so gonna probably limit it at 8000, and yeah HKS super header is what im probably gonna go with

have you researched whether the 308 degree cams will interfere with the shims? Or have you got an under bucket shim setup?
<div class='quotetop'>QUOTE (drftr86 @ Dec 14 2007, 10:34 PM) </div>why would u run cams with that kind of duration unless it was a pure animal track car which it clearly isnt....i think it would be more sense to run lower duration cams (272 or 288) and simply built the head for more lift...

Also, by limiting the rpm to only 8000 to save the bottom end is a waste of the big cams as they need more revs to produce the power!
