i just had package done to my car a few months back, heads/cam, intake manifold, all the boltons i could think of. stock bottem end though. The car made 505rwhp/441lbtq, the build used afr 225, comp cam, fast intake manifold, the compression now is 11:0.1. From what im told the engine is maxed out, i can run maybe a 100shot, but thats rolling the dice. I was thinking about switching out bottem ends, but i would like to keep my heads and cam ect, not have to get a whle new set-up. I dont want to run nitrous or go FI, but it looks like im going to have to to hit 600rwhp. If you guys could help that be great, i dont know alot about cars, but i figured building a stock block would be able to hold no2, even if the comp is bumped up. couldnt i just put a thicker headgasket on to make up for the comp, if i wanted to run no2??
