330 Olds V-8 forged steel crank in 403?

Does anyone know if the Oldsmobile 330 V-8 ('64 - '67)crankshaft will fit a 403 Olds block? It appears as though it would seeing as they both have small ( 2.498")
main bearing journals and the same stroke (3.385"). Only noticeable difference is the bore. thnx

It all depends on how each is balanced. Call an engine rebuilder and ask, most are happy to give out the info if there's a possibility that they may get your business.
