2019 summer race.... Jadaharabi vs 318willrun

How on earth did it go all the way around the piston like that? It looks like the piston was rotating.

It had to be spinning, it chucked the lower 1/2 of the rod threw the block, I guess the stub of the connecting rod was hitting the counterweight, which made it spin.
The engine never did lock up.
The head was actually fixable.
