We pulled the motor in May to rebuild the heads. it only had 130 / 170 compression and wouldn't idle right and was running on 7 cylinders. I got the heads off the cylinders appeared to be ok, they still had hone marks in them and no ring ledge. After rebuilding heads and putting in the water at Havasu it run very strong, then started smoked to like crazy. So pull it again sent it to Speed o Motive in West Covina, CA (They built the motor in my Cobra 408W) had it maged, that when we found the crack. They said it wasn't bored straight? Come to find out the block was bored .60 over but the piston were only .30 over. I have been told some marine engine are set up that way so they can run at high RPMs?
I think I'm going put the block on eBay and buy a new Genisis block and be done with it. The motor is a matching # 1963 427 Center oilier built by Clay Smith Racing back in the 70's.

Thanks for all your input.
