.060 under for performance use.....hmmmmm.....dont know about that. I have heard of the .040 cuts on cranks for standard service, mom & pop grocery getters, and thats no problem...but yeah, the nitride coating is long gone at that kind of cut.....so crack prone possibility

it will not be past the nitride hardening it.s not a coating many Gm cranks 283 and 396 some 454 that were steel never were nitrided or if its a iron crank . it will not crack or be weak if the radi is round in the crank . the first thing on some race engine is to use smaller mains and rods like many use a honda rod bearing .many on here over think this that engine will never know if its a std crank or a 030or 060 it would be nice to have a std/std or 010/010 less you give him one i thinking he going with what he has
