I think ill stick with BBC. Just a small one though, like a 396 or something. I don't want to make enough power that I can't use a th350 because i already have one built and ready to go...Plus, im looking for good street power, not drag racing...I want something that sounds pretty, looks pretty, and i can romp on it. I'm shooting for about 400 horses and from what i can tell its pretty easy to get that out of a 396.
