Not Ranked
The engine is out, here are some pics:

This engine had a custom balance to it and it's very possible that when the original dampner broke last year and we tried to have a machine shop drill the new dampner to match the balance, it wasn't quite right (although we didn't feel any vibration). The slightly out-of-balance damper caused the crank failure, which wiped the mains. Hard to say the order of events.
Maybe someone can explain why any engine builder ever uses non-standard balancing?
