You can do it that way, but you end up with thousands of dollars in them. Not only do the snouts have to be turned down, but the flywheel flanges too, in addition to converting the rod journals to BBC.

The custom Scat has undercut pendulums, gun drilled mains, scalloped flywheel flange, and only weighs about 55 lbs. Plus they make it to fit your bobweight so it doesn't require $700 worth of metal like the 391 crank can.
