Cool, thanks a bunch for your help. Is there a place to order a new block from then for the 420A, so I can build one without my car being down? I have been looking on Hahn Racecraft for a while, but my roommate with a Supra was telling me other information. Cool, I will go with my original idea of building my motor up by doing the bottom end then. Guess I will just let my car be down for a while or see if I can find me a new block. Thanks again, Dan.
