I would diagnose before you sell, part out or fix. Roll the engine over w/ a 1 -1/16 wrench on the ps pulley clockwise i think, check to be sure. If you don't find an interference, check the fluids & try starting again.

If say worst case, you broke a valve and shredded a piston and the head, so you need, piston set, rings & head and your body is good & solid, then I would look around for an engine from a deerhunter or similar totalled vehicle.
