ISO 4.625 stroke crankshaft what's out there
Looking for 2) bbc 4.625 stroke cranks. Long shot to buy used but thought I'd throw it out there and see if anyone has 2 collecting dust.

If it checks out and standard mains and rods. . Bryant, crower or callies not to worried about it. Sometimes people have new stuff laying around because they went diff direction to 4.75 or 4.5. But I'm good with used. Not much different than buying a used engine and rebuilding. Every boat out there for sale has used cranks in them.

Basically with new parts I feel there can potentially be more risk. In a nutshell new or used I always have rotating assemblies and blocks cked over by shop - shot preened/magnafluxed. Several years ago I purchased new crank and rods for a build. They were middle of the road quality however crank was bent slightly and one rod had hairline crack. Not a casting flaw but a crack. If it wasn't for radio using the beams and polishing them it could have been easily overlooked.
Regardless new or used I always take precaution. Regarding original OP if you don't have any luck call molnar. Quality cranks and rods with excellent customer service. They do an excellent job with their crank grinding and polishing.
