Is that the only cylinder that broke the sleeve and block?
Hate to see carnage!
How much would it effect the weight distribution of the car going to an iron block?

Honestly, if your tuneup was right and you had e85, this wouldn't have happened. Just something to think about, people always like to think meth is cheaper, but the number of stock shortblocks that die on pump gas/meth motors is a lot more than e85 IMO.

Wasn't a hot spot or any of that crap. Obviously this is top ring issue on clearance. The compression ring butted ends, wobbled and bounced, expanded then pulled off part of the piston crown. Nothing more to see here.

There are no signs of detonation from the images posted. Looks like metal fatigue failure due to binding.
I would recommended pulling the damaged piston looking at the profile of the metal surface of the compression ring and 2nd ring. The story will unfold from there.
Look for lateral and linear rough surfaces on the compression ring surface. And on the end gaps look for dulling of the edges.
If you have bad eyes go to radio shack buy magnifier 10x for $8.99

Sureeeeeeeeeeeeeeeeeee it was detonation.... cleanest damn burn I have seen. There is no pitting or spot of the piston surface. And you say its detonation? lol
The piston ring was pulling off due to binding/metal fatigue. Not detonation... Detonation cause pitting and carbon to fry to the piston surface as well as fracturing. This was not detonation.
Pull the piston and look at the ring surface to get to the bottom of this.
