One piece rear main production blocks are junk if they have lots of miles on them. I have thrown away a few dozen blocks that would not clean up at .060 over. I have also found ones that would clean up at .060, but the wall was too thin on the thrust side. I am not trying to discourage the use these blocks, but a thorough inspection of the block is a must before even considering purchasing any parts. Two piece parts are easy to find, cheap and it is internally balanced. Whats not to like about that?
