Goodbye piston...carnage pictures inside...
Goodbye piston...carnage pictures inside... Well, I am sad to say the motor in the T/A blew a couple weeks ago. 
Today, myself and two friends took apart the top end and were surprised at what we saw. Can anyone explain what might have happened? Either way, here are some pics. It will be interesting when we take off the oil pan.
Intake manifold...stock with metal chunks...
It looks like the heads should be salvagable...
This is where I stand now. I guess I am looking at a new block and bottom end.

I think when we pull the oil pan we will find the main chunks in there.

The almighty LS1 - even it cant contain its greatness! Sorry, cheap joke at your expense.
Man, that is horrible. Have you done any engine work to it lately? I mean, maybe something got inside there and caused excessive heat in/around the pin causing the piston to fail and then grenade. I dunno, Ill leave the speculation to the experts but that is crazy.

That is, unless you were looking for an excuse to go LS2 402 w/L98-L76 top end. 
similiar thing happened to friend, turns out the ring broke and broke
ring land, rest of the piston follwed, ende up in the oil pan, but since it was iron block, it was rebuildable, caught it in time, .030 over bore cleaned up the cylinder, was a4 trans.
same thing may have happened to yours, his car was maybe like 360rwhp
if at all , nothing fancy, just badjuju i guess.

Wow - I have never seen a piston explode like that!
Did you recently do a tune, or change anything on the car? Any other symptoms before the explosion( SES, oil pressure, water temp, noises, ect)? If no, then I guess it would have to be ring-related.

This might be a dumb question, but could I do a 408 block and reuse the trick flow heads and top end that I have now? Would the heads even line up to fit? I know they wouldn't flow as well, but it would be better than another 346.
