Default RPM 4.375" stroke FORGED crank BBC

I have a Forged crank here, mad by RPM 4.375" stroke, was in a running engine, needs polished, maybe cut .010 worse case. This uses 2 pc rear seal, can be used in markIV blocks, this was in a gen6 with rear main seal adaptor, so can be any BBC cost 750.00 new, selling 350.00 plus shipping..

Would the 4.375 stroke work well with a 4.310 bore? That would give me a 510.

Maybe I don't really design them but the most stroke is good normally if it fits...
