Yeah I've done buisnes w/ Jim shafer he and his shop is absolutley the worst engine builders around DO NOT BUY FROM THIS CLOWN!!!! I made the mistake of buying a SBC from him last Feb. 2004. and I'm still trying to figure it out. what an idiot....They took 3 months suppose to be 1 month to build my engine. When I finally got it it was missing oil gallery plugs, rear main seal was wrong and leaked everywhere, wrong timing chain installed and incorrect cylinder heads. I could go on and on but if you want to hear more email me, I'd be glad to let you know about them. I'm a little late on the post but hopefully you haven't bought anything from them.
