Right, but if you(the OP) mean a later heavy truck/motor home 413 crank, it may not. Most(if not all) of those motors were reverse rotation with a gear driven cam. They will leak at the rear main seal because the 'sipes' cut into the crank to direct oil away from the seal will work backwards and flood the seal with oil. A crank shop can usually fix this.
