FAST 90/90 V's PORTED STOCK
 

I have a stock ported LS6 intake and stock TB what kind of gains should I expect out of a fast 90/90 intake and TB? The car runs well as it is but I have been wanting the 90/90 for a long time. I know the Fast 90mm intake and TB are a little big for stock cubes but I do have a kinda big cammed LS1. The cam is a 233-239 / 602-605 on a 113LSA. The car runs low 10's now on spray but I want to get away from spraying it all the time. Sense working on getting it faster on motor we have it running 7.3's in the 1/8th and with out going into the bottom end the last thing is the intake and TB. Any other details are in my sig.

Maybe another 10-15 horse, considering you dont have the heads to take advantage of their full potential..

I have PRC 5.3 stage 2.5 heads. You can see sig for all mode.

its not too big for those cubes,you will pick some power.you can use a fast 92mm also if you can't find a used 90mm intake.go to the used parts section and look for one.if you find one get alot of pics of it to make sure it ain't damaged.
