    I have finally found a 6.5 block that doesn't have cracks in the mains, but it took a part of the piston crown off and scared the walls on that cylinder. Have any of you guys had one of these blocks sleeved? Also the crank has some minor scratches in it. Is it bad to have one of these cranks turned or would you just give it a good polishing and run it?

    Doesn't hurt to sleeve the block, but the crank should not be resurfaced. The crank journals are filted, Resurfacing them will weaken the crank. A polishing will be fine and will not harm the crank. hope this helps.

    thanks the crank has some scars from where the rods were taken out before I had gotten the parts. So I guess if the polishing won't take it out look for a different crank?
