I was just thinking ahead for my next project. Would a Fast90/90 be too much air for stock heads with a medium cam(~224ish)? It definitely helped on my old setup of ported LS6 heads, and i know the stock 241's flow pretty damn good. Just curious if anyone has any first hand experience of this setup.

 

pretty heated arguement.

there was a thread recently about it. but i think it was figuring a bigger cam than a 224.

you'd probably see a little power up top, but not enough to warrent the cost of the FAST 92/92

save your money and just stick with an LS6 and a ported TB

 

you could always grow it the intake, yes it won't be optimal right now, but everyone eventually gets some good heads and then next is a forged bottem end and with a 408 not being much more than a 347, you could up your cubes. then your 90/90 will be optimal.

 

vengence seen a gain of 29 rwhp on a stock motor with LTs and exhaust. using a ported 92/92 combo. this was on a ls6 motor

 

I run a 90/90 now with stock cam and stock heads. Car picked up .35 in the 1/4 mile consistently compared to it's previous best. But I was running the LS1 intake prior to the swap, not LS6.

figured why pay money twice and change out intake twice..

 

I already have the 90 setup sittin in my garage so i won't have to buy one. I had it on my old setup and figured i would save it for the next one.
