I'd like to see the engine up close - it's interesting. If all the pushrods are bent, I'm more inclined to think a valve-train issue started all the trouble. I had a big-block 454 that lost a valve retainer, then had a piston hit a valve, then the timing chain came off, and then all valves and pushrods got bent or broken - and also bent a rod.

I've got a couple of 6.2s and 6.5s in my junkpile with bent rods - but that happened after a main-bearing web support broke off the block and the crank broke.

Also got a Deere 4020 engine in my junkpile with two severely bent rods (can't remember what caused it though).

I think rod breakage in 6.2s/6.5 is pretty rare - unless caused by some other calamity. They have forged-steel rods which is a plus. Unfortunately, the cranks are NOT forged - just cast-iron.
