I grenaded my slant 6

The engine block looks pretty clean. Was it rebuilt recently? If so about how many miles were on it?
Looking at the pieces in the photo, is the shinny piece a part of the piston from the piston pin end?
It would be interesting to see more of the carnage pieces to see where the failure initiated.

Yeah the engine was rebuilt this year, maybe 2,000 miles on the engine. That shiny piece is what I found sitting with those two parts of the block on the side of the freeway, i think it's from the piston pin end, not too sure yet. As soon as I can I'm going to try and figure out what happened
