well its not really that much to bore and stroke a engine, but since you have to pull the engine, rip it apart, buy new heads, rings, pistons etc. it will run around 2 grand! but hey its worth it! And i like how you put it "5.7 liter 350, not a corvette engine" I hate when people have a 350 in a suburban and then they tell me its a corvette engine, i tell them, its a corvette block, but by no means is it a corvette engine!
