360/440 cast crank manual flywheel

Never saw a 440 cast crank with a flywheel. All the ones I've seen had forged cranks if they were in a manual trans vehicle. All the cast cranks I had didn't even have a hole drilled for the pilot shaft or bushing. The photo above just looks like one for a forged crank. that little cut in the edge was just to neutral balance it. You'll see that in other applications too, along with small drill holes that do the same thing.
