It obviously destroyed the piston, broke the rod, blew the cylinder wall wide open and also cracked the crank. The only major engine component that was salvageable was the driver side head. It was nasty.

I was in the garage when it happened. Engine was still cold. I was at 12-1500 rpm. My choke sucks sometimes so I try to help keep things going. Had about 30 seconds of run time on that start when the shinola hit the fan.

I was probably at somewhere between 3-4K rpm when it came apart. Like I said, it was ugly.
