500Hp out of a Ls1?? Hi there im new to the forumn..Just wondering what it takes to get 500HP out of a stock Ls1?? Are we talking heads, intake,cam injectors etc? This would be going in a sandrail so im not worried about exhaust..Thanks for the help
solid roller, bad *** heads, big cam, lots of rpm (which will be beneficial for you anyways), injectors and some sort of sheet metal or carb manifold would be nessecary also...well, not nessecary but beneficial.
I am running AFR 205's milled .030", Comp XE-R 224/228 .581"/.588" 112LSA zero advance, SVO 30lb/hr injectors, LSX90/NW90, Kooks headers and cats, Borla Stingers, through 4:10's and just dyno'd 440rwhp. That comes to ~517 crank hp. That is a small cam and the car is a great street setup. I would suspect that with the right setup as outlined above you could easily pull 600 crank hp on pump gas, well, 104 octane pump gas. There is a forged 346 LS6 twin turbo vette making 1050rwhp, and there are some f-bodies making that and more.

you dont need a sheetmetal intake or solid roller. LGM, Cartek, TR, TTP, Rapid have all made 500+rwhp with 346-348's. you'll need a good set of heads, i recommend a set of AFR 225's, some compression, a cam to match your setup, 90/90, and the rest of the bolt ons, plus a really good tune.
however i'd opt for more cubes, either 383 with the ls1 block or go with an ls2 and do a 402.

Some people relocate the coils to a fenderwell or firewall and run longer wires in order to clean up the engine compartment. It does look better but I don't think the extra wire length and resultant resistance increase is worth it.
