I've never heard this thing rattle, but I hardly ever drive it. My wife knows her ****. Been racing her whole life. Did have too have it retuned 3 times because of corrupt tune. That's what dealer said.

Would the stock lifters work with the HOT cam?? The springs look to be beehive, but I can't get a feeler gauge in them at full lift. I have been all over the truck today at the dealer. I think they reused the stock lifters and springs with the GMPP cam...

Detonation does not have to mean lean burn down. Those are very different things. Seeing as our new fancy computer controls have methods in place to prevent these disasters from happening we can tip toe closer and closer to the edge without fear. So if your engine was tuned by some hacktard and say the trouble codes were turned off and the tune was bad. It could still be detonating badly and not throw a code to warn you of this. Plus once it detonates it will go into knock retard and retard the ign timing which would stop pistons from melting. But the engine still has to endure the impacts of detonation and by the sounds of things it only took two years of pounding the **** out of your poor pistons until they decided enough was enough. Not saying this is exactly what happened but it sounds very plausible considering the facts you've offered.
Was there any ptv contact marks?

Not necessarily. Cooked engines are tricky to diagnose in person let alone guesstimating over the internet but I'll throw an opinion out there.
