You would need 425 - 450 rwhp to beat a stock GT500. Even with an aftermarket supercharger, you would weigh in about 150 lbs less than a GT500.

That, of course is for a stock GT500. IIRC, GT500s can put down over 500 rwhp with just a CAI and tune.

when u added up the numbers to 174 HP that's not correct... not everything works together to make percect adding like that... say the website says 30 for p&p heads and 30 for cams... that doesn't mean u will get 60 from both, more like 45-50 depending on cam specs. shorties are worthless, the throttle body and spacer are worthless, only thing exhaust wise that will give you any power will be longtube headers, and a little for a catless midpipe... items 9-12 i've heard nothing about so no input... if you want to stay cheap and have high end speed go centri, like the paxton, but i prefer ProCharger... but if you want some low-end torque and really fun street driving , get a twin-screw like a whipple, KB, or saleen... i would stay away from the roushcharger being a roots blower it runs hot and is less efficient that a ts... now if u supercharge your car, which hopefully you do instead, make sure to get 1 3/4" primaries on your LT's, i suggest American Racing headers. that's it in a nutshell but there's much more to learn... do some searching on the forum

All I can say is WELCOME and read more, my friend. Good luck to you. I have no doubt you'll turn some killer times when you're done... Wait. What am I saying??? We're NEVER done...

Numbers just don't seem to add up for what you have listed. If you wanna compete with a gt500, strap on a blower and a few additional mods should do. N/a just won't compete. Whipple, KB, or a Saleen would be great add ons.

I agree. Forced induction all the way!
