My avenger phantom hybrid

I'm at a loss how that even happened, obviously it was loose debris in the engine, but for gouging that deep it's remarkable it even ran long enough to sustain that damage.
 
I would need more and clearer pictures to figure out what happened there. Something definitely broke off or came loose. If both tangs are on the wrist pin clips, I would think maybe a piston ring pin came loose or possibly one of the rings snagged on the transfer and broke off.

When I get off work Ill get some better pictures in the day light.

Here is better pictures of the destruction
It looks like the ring pin came out. What piston did you use?
Duke preformance coated or something like that. I ordered a ms460 hyway piston and another phantom 85 cylinder. If anybody can tell from the picture how nit to do that again please let me know. Thevonly thing I know was wring for sure was one of the head studs striped out and I couldnt torque it properly oh and if revved up really high so I come to a stop still reving high I was trying to turn down the Idle but i guess I took to long then I heard a noise and I shut it off.

Need better pics of the cylinder & the piston to get a better idea as to what happened.
