the strength loss by grinding is minimal 'IF' the proper radius is maintained. There will be a loss of hardness but that is not an issue for most applications.

It is common to turn these BBC cranks to small block size rod journals. Bearings for small block rods are available to .060 undersize. Big block mains are good to .040 undersize..
