Re: LT1 Block

LT1's are easy to make power with, id sugest you keep the stock cast heads, like i said they outflow stock aluminum ones, and with some porting they can make some power. run a bigger cam, something like the LT4 cam(wit matching springs) would be a great cam i think, you probaly have to punch it .030over so if you want to spray it youll want to run a flat top forged aluminum piston, upgrade you main and rod bolts to ARP's, run some bigger injectors maybe a 58MM throttle body, and a good tune id say you could probaly hit 400hp
