Fordged 318-3 truck crank or Poly crank, need help ID

It'll WORK. PERIOD. IF the crank flange is really thick, it will not have a flywheel register. This is a simple fix for the machine shop to cut a flywheel register on the flange. There is enough meat to do it. I've done if before myself. Also, don't worry about "the crank throws are solid it'll be heavy blah blah bullshit bullshit." First off, I can clearly see the throws are not solid. Even if they were, just balance her up and let her rip. The extra strength you would gain would far surpass any negative issues regarding weight. Besides, it's fairly close in to the crank centerline and therefore not as critical as say a heavy *** mafungo piston swinging in the stratosphere at 7500 RPM. Run it. It's billy badass.
