I've owned a couple late model F-Bodies, as many of my friends have also. I used to roll 20-30 F-Bodies deep through TX with LS1.com members all throughout the week to Hooters gatherings and lunches. I can tell you I am wasting no time with N/A performance in this 96GT I just picked up. Its getting a blower and I won't stop until the car is putting out 450-500HP with ease. With what I've heard about KB blower's, those numbers seem to be easily achieved....
Come on over to the Modular Depot. KenB's car rocks. So's Starkie's and John Edwards'. You're looking at all NA cars with no more than .020" overbores with 2V heads going 11's with mid 300hp power output to the wheels...
it is all in the combo. I have seen anywhere for 300-340hp. I have seen higher with compression and other mods I think ken b over at the modular depot is up to like 362 or something rediculous like that.
bottom line is boost is cheaper in the long run but i will admit I am a sucker for a n/a car.
