my lil 6.1 died at the 1000ft mark at the track

stock engine. just a mild, slightly better cam. Behive springs. Everything else is stock.
I have no clue what this caused. In the Facebook Group Gen3 Hemi swaps i posted a few Pictures. It Looks like a granade exploded in the block...

I am still collecting ideas what did cause this...

No power adder. In case of asking. I run 102 octane fuel. Ignition set to 26 degrees
