Yeah people are always replacing their motors with bigger ones or an LS swap this days. Probably could get a decent running one fairly cheap and drop it in while you decide. And then when you get your other one finished you can sell it off to the next guy. I was going to keep a spare loaner motor just in case someone was in need but that plan went south and I found myself in need. A good friend had bought a motor last year that he had decided he wasn't going to use after all and he is letting me borrow it for the summer. How cool is that? Finished the install last weekend a took it for a drive around Saturday. Runs fantastic. I think he said he paid $2200 for it. Probably a bit more than I would've paid but it's a 455 with low compression heads so you could run any kind of gas you want. Plus the guy said it was fresh rebuild and by the way it runs I believe it.
