Aight so first off I have 87 iroc z the engine is slightly modded brought car like this from a friend that had all the paper work.so 350 tpi bored 40 over 2032 cam,dart aluminium heads pro 1,1.5 roller tip rockers.#24lb injecters and a afpr and ofcourse headers/full exhaust.the tpi intake is stock but it looks like it's been ported.But look like a shitty porting job.So I was thinking aftermarket base and slp runners and 1.6 rr? What y'all guys think?

 

But just a guess,what would this setup bring to wheels? I know my bolt on lt1 with iron heads made 258whp ran 8.7 in the 1/8th full weight.the iroc feel faster but no track time yet.Hell I can't get it to stop spinning the tires.even at 20 to 30 ish stomp the gas and tire spins then it hit 2nd and spins again lol.The 255 tires ain't doing **** for traction haha
