intake,bigger tb ported by potz or any 80-85mm, air lid,maf ends ported or new,and do the heads and cam.This will give you at least 40-60 rwhp extra. Why pay $1000 for a Fast and gain a so called 20 rwhp which you will not get unless you have cam,.heads anyway.
Remember an ls6 is good up to 450rwhp and lets face it majority of us would be smiling ear to ear with 450rwhp for a long time.

That's one particular car...I would like to see a back to back dyno test on like 3 cars at once...one bone stock ls1, one with cam only boltons, and one full race all out h/c/I....to me that would give an idea of how much a fast will improve over ls1/6 intakes...I would like to see where the ls6 actually restricts you..

When I was cam/boltons I had the ls1 intake and went to a Fast 90mm with typical porting. Throttle response was up down low just a tad, but over 4k rpm it was a whole different car.
Rough estimates based on track MPH is 15-20rwhp with a reverse split cam.
