Jimmy, welcome. I just bought a 428 that runs great. I was just going to switch out heads pull oil pan and inspect. When I pulled the pan everything looked good. So I decided to pull a couple of rods to see if ok. I found some scarring on crank and over. 003 clearance. So as of right now the block is getting bored and crank is getting turned. This motor had been rebuilt at some point but not very good. I would at least freshen up the motor. If you know the history on this motor of yours you know what has been done. All the seals have to be worn out. Gaskets must be to. To me you have only one option rebuild the engine. You will be happy you did. Trust me. Joe
