I'm trying to weigh my options, i'm still going to use my car for daily driving just simply put i'm looking into a 400-800hp range motor. Although it's a little tough trying to figure out which route I should take.... I could go with a straight up LS1 Bore it to a 405 which could be quite cost effective... Buy a LS2 (A little more pricy) and work it up or go for either an iron 455, 428 or 400 pontiac motor (since it's a pontiac). I'm hearing good stories about 400's they are still cheap and there are several stroker kits available for them..... If I go LS1-(2) i'm def. turbo'ing it (twin or single stage turbo kit)..fuel injected or carb'ed?.... opinions ideas would be greatly appreciated......
