back in 2002 a friend if mine found someone in hemming's in NJ to build and swap the motor in her 76 grand Prix.it sounded all kinds of sketchy and she had sent a deposit etc but went down there,met the guy @ the machine shop he was using/saw his place and it was legit.the whole thing went well.I'm not saying that guy's still around but you never know.have you checked craig'slist?
