Oops..piston gone
Now what?! I just put new heads and cam on the Z06 a couple of weeks ago...and I was playing around on the road and looks like a shot a piston. Any suggestions? New bottom end or new pistons? DAMN IT!

Well if you didn't scar the walls you could get away with just pistons, but either way I would do the bottom end over pistons, rings, rod and main bearings, and oil pump.
Or just go the short block route, that you have new heads, it would be quicker that way.

Is this a good one?

My heads and cam are both from TSP.

That is a good engine, my friend built a ls3 out of a 09 vette. It was a very good all motor build with a lot more left in it... He put a super conservative tune on it and made 551 to the ground. He has a stock manifold on it still also. It was also built to take a 150 shot on the aggresive tune... So basically it is capable of well over 650hp.

If he "holed" a piston or damaged a compression ring with a naturally aspirated application it was because the combustion temperature was more than likely way too high (at least on the aforementioned cylinder) which resulted in detonation. Some of the possible causes are: too much spark advance, poor cooling (cylinders 7&8 are notorious for this), lean condition, too high of a compression ratio on low octane fuel, piston weakened by fly-cutting. The stock LS6 bottom end can easily support the power produced by a well planned heads/cam set-up (assuming it is properly tuned). I would be very interested in seeing some pictures of the damaged piston.
