The crank is .0002 under the max. I calculated if we align hone the block, and put it on the max, I will have .0018 clearance. That's using the Sealed Power bearings which I actually measured. In my experience Sealed Power bearings measure thinner than Clevites. I don't feel comfortable with .0018 on an original 455 SD engine/car I'm shooting for .0023 -.0028. The pistons for it are going to take 10 weeks so I guess I'll see if Clevite gets the extra clearance bearings in stock between now and then. If not, I may take it to a crank grinder in town and see what he can do. Scary!
