There were rumors flying-around that there WERE some MH/truck 413's with 8-bolt-cranks .. but I have never seen one OR heard of someone actually having-one. And I have quite-a-few of 'em ...me-self !!

BUT ..it could be ...



I own one. It came outta my old 413 Marine. The 8 holes are NON-threaded; it used bolts & nuts to hold the flywheel on.
Also, the rear flange - what the 'wheel bolts to - is extended an extra 3/4" rearward.

I might have a pic floating around....lemme check.
