Be sure to have a speed shop test the block before you go getting it bored, my speed shop told me about core shift, basically the core of the block was just barely off when made, it turns out it is 9 thousanths off on 3 cylinders, so if it's bored out, it will be worse. Having to find a new block now. He also told me that most of the sportsman blocks you order are like that too. Sonogram and magnaflux should only be about $50-$75.

Oh, my vote is 331 cause it hasn't been around that long, plus I'm gonna turbo it to death. 15psi!!!!!
