Forged steel crank from 1968 small block Chevy 327, large journal, not drilled in nose, it was ground to .030 on the mains and .010 on the rods. It will need another grinding on both as there is some wear on the journals. It looks like it should clean up, they can go as small as .060 under. This crank can also be taken down to small journal dimensions. It is casting number 4672.
