Hey fleetwin! Long time
The scary part is that engine was running..
I Talked to the owner and there’s no point in continuing to try to run something so damaged.. it’s just going to leave him stranded somewhere at some point.
At least at this point the Pistons may have some value .. connecting rods have value.. the crankshaft is great still, reeds good, head good. and he can sell the block to someone who wants to bore it out.
The secret here is to park these motors up before they self destruct, As the internal components will be almost worthless once they’re damaged more. 
so I disassembled the whole engine. Going to part it out.
