767Jockey If are going to get another new block, ask them to bore the cylinders to spec. This way the only thing your machinist has to do is a final hone job with the correct stones to match the piston rings. Just a thought?? Rick L. Ps I am sure they will sleeve and sell the block going back to someone else. There should not be any loss except for the shipping to the company. I hope they fired the putz.
