Block is good, heads are good.

Port head gasket let go and water mixed with the oil. There were women and children onboard at the time so I ran it toward shore til it popped. I believe a con rod snapped. The engine was at low RPM (1500-1800 ish) when it took its final breath. Poked a hole in the steel oil pan but no other damage to the block.

I can deliver for a fee...beer and gas money is fine. You are also more than welcome to pick up from my house. I will help load if need be.

Shipping is entirely on you. I'll put it on skid but anything after that costs money (wrap and strap, etc).

Engine is clean, all hardware is in great condition. It is my belief the builder did not torque the heads properly and the head gasket deteriorated.

Excellent candidate for a long block rebuild or sell the heads and pocket a few hundred.
