Hi Brian, difficult to tell from the photos without actually having the unit in front of you but it appears the crank is not located correctly front-to-rear in the block??

If you look at all the rods are they all "off" in the same direction, is it right and left banks, or is it random??

The "fix" to at least that problem to make it work isn't that difficult but the rods and piston must be separated. You could "side-grind" the pin ends. We do this occasionally on the belt sander! You just need to be real careful not to "upset" the pin bushing!

Thanks, Gary in N.Y.

P.S. What exactly was the main brg issue??? We don't use Scat cranks (for other reasons) but we do use their rods. This isn't your issue though.
