Thanks for all of the replies on this topic. I just tore down the 36LB engine in question. It is .040" over with no cylinder ridge to speak of. If it has no cracks I'm going to leave it alone.
I have another cracked LB block to mess with. If I can locate a 4" merc crank that is way undersized or has journal damage on the mains I'll grind the mains to the LB size and find out for sure what works and what doesn't.
Thanks again.
