Cab, I feel much better now. That was my SECOND big mopar lesson I learned. My 340 warranty motor in my AAR had the same problem. I took it to the wrong machine shop on advice from my old SS engine builder. This was before he opened up a full shop. I started the cam in with a hammer! It would not turn at all, fortunately. Lol! I took it back and they fixed it. My oem cam would fit but not the new one would. I was told back then it was simple core shift from all the heating and cooling cycles. My first mistake was the old pilot hole in the crankshaft was too small because I had an automatic crank. I just drove in the bronze bushing and shrunk the id. Like to have never figured that one out.
