One thing I somehow missed was 286481 is the Steel Flywheel 8-Bolt Crank.
286480 is the Nodular Iron Flywheel 8-Bolt. So thats why the 286480 are so much less.. Think I'm leaning towards the ford racing one, just cause when I called FRPP thats what he recommended, but they would anyhow.
Not an expert but I know strength is a big difference, nodular are cast. I'm planning at this point to go with my stock coyote flywheel figure it was good enough for the mustang and at this point I don't plan on launching the truck that hard.
