Whats up fellas! My name is Mack. I have a 85 IROC that im putting a LS1 into. Im not a newb to cars and motors in general, this is just my first time dabbling in the LS world. All i have right now is the complete block. I decided to go this route simply because i wanted to build it up from the bottom my way. My goal is to make at least 450RWHP, anything over that would be icing on the cake. So i guess i'll start by telling you what ideas i had an you can give me some feedback. Ported LS6 heads with all the goodies, all the bolt on goods(headers, throttle body, etc..), a big cam(not sure of size or brand, need help on that, but i do like a choppy idle...lol), injectors-rails-fuel prs reg, & msd. Im sure i have more stuff on my list, but i cant find my notepad...lol. But that kind of gives you a idea of what im thinking. any feedback is appreciated....


I posted this in another section, i got a lot of views but only one reply. i know people are helpful on this board, because i used and watched it before i joined. lol...so i decided to try a little more popular section.


thanks in advance!

Not sure why they moved my post here, im not asking for installation help. I figured this would be general information since im only asking about a motor. Smh...

450rwhp is easy with a manual trans, i make a solid 422rwhp right now with crap heads and a small cam.

with a stock bore and stroke ls1 (346cubic inches) i would suggest a good set of heads, 243s should be fine, a good set of dual springs, fast intake and throttle body, at least 90mm on both and a decent size cam.

with that being said there are alot of cams out there to choose from, thunder racing, texas speed, vengeance racing, etc are a few big cam companies along with other things. with the parts listed above and say thuder racings max effort Raptr camshaft .615/.615 lift with a 111lsa will get you to your power goal if not more. and it has a very nice choppy idle. or you can contact Pat G for a custom spec'd cam if you dont care for off the shelf grinds.

If your planning on an automatic be prepared to sacrafice some power.

hope this helps.

Unfortunately its auto, but the upside is im not building it to be a drag car. lol..just a fast car. i know as far as LSs, AFR & Patriot are suppose to be good heads. any other brands out there worth looking into?
