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
330 Olds V-8 forged steel crank in 403?
