so, I ended up settling with GM for the entire amount of the engine replacement plus my lawyer fees. Anyone need a good lawyer, I got one! I put about 3500 miles on motor and then went out to Auto Club Speedway and.... blew a hole in my block... unbelievable...

First, go talk to a lawyer. It doesn't hurt to talk.
One of our cars blew the motor a few years ago and they said they would not cover it because there was only 1 qt of oil in the pan. No signs of an oil leak, so we must have abused it. My wife called the lawyer and faxed him all our maintenance receipts. The lawyer sent a letter and followed it up with a phone call a day later. The general manager called my wife and said they had reevaluated the issue and they were shipping in a new motor ASAP.
If you have any motor skills it may be a great experience rebuilding yourself. If you don't, find a friend that does and take the opportunity to learn.
Replace the cast hypereutectic pistons with forged pistons and tool steel wrist pins. Also replace the 2-piece exhaust valves with quality one piece valves and the steel valve guides with bronze guides.
Best of luck!

An LS7 costs a lot of money... most engines do as a matter of fact. Taking the time to REALLY see it all and understand it is worth more than the motor by far. If you have the time and another car to DD I would rebuild it with the best parts and do it yourself preferably with a buddy nearby that knows engines if you do not. I promise it will be an experience like no other... aggravating, rewarding and exciting like you would not believe.If you are worried about anything during the process you have an entire forum of builders eager to help out including myself. If you can spare the time and the patience I would not recommend anything else.

So this is a second blown engine for the same owner. He got 3,500 miles out of this new one.
I said it once, and I'll say it again. A disproportionate number of these engines are failing among the membership of this forum and anyone thinking that there is not something going on with some of these engines has their head buried in the sand.
When have you ever heard of someone in here having an LS1, LS2, LS6 or LS3 fail, getting it replaced, and then having that second one fail 3500 miles later?
While I am glad to see that more and more people are not bashful about asking for verification on some of these failures, despite the fact that others took a pounding for initially suggesting it, this one has at least one witness who is a long time member of this forum. So you have the word of the original poster and a long term respected member to confirm it.

I really love the old fraise "Lightning never strikes in the same place twice..." Yah ok so you'r saying it found the quickest route to earth to ground itself (as electricity does) and next time it's just going to opt for a more difficult path for the hell of it? NO! It should be "Lightning is likely to strike in the same place twice or more than twice." Anyway sorry for the semi thread hijack! Hah.

This will certainly set a precedence.

I've seen a z06 blow 2 motors in a month. First one lost a bearing. Dealer replaced the shortblock under warranty. They didn't replace the sump/cooler. Second motor lasted 700 miles before it lost a bearing from all the junk that was left in the cooler/etc. Dealer then replaced the motor along with all of the oiling system to make sure it was clean.

I'm sorry, I read it thru quickly. Didn't see anywhere mention that the block was toast.
R&r is typically 600-1000. Figured parts and labor was 2-3k depending how bad.
But ya never know how bad til you're into it.
Sorry for the confusion.
To the OP, I'd just buy a built motor from the board here and slap it in. I had a built 427 that I was selling for 10k, would have worked for ya.
Good luck.

One question to the OP, did the shop/dealer replace all oil system components after the first engine blew? That would include the oil tank, all lines and especially the oil cooler. I know that when I blew my engine, the debris went everywhere in a hurry. The cooler, lines and everything that had oil running through it was covered in sand sized debris.
Does you work order from them clearly show what was replaced or cleaned?

Also, was the second engine failure on the car's stock tune?
Third, do we know yet for CERTAIN that this is a catasrophic failure with the 2nd engine?
To the OP, really sorry to hear about your bad luck, I would say its time for a ZR1 or a 600HP 2008-10 Viper!

Today I got some pictures after the head had been removed. Damage is pretty severe but not as bad as I thought it would be. GM Rep looked at the engine today and approved warranty replacement, told Service Writer to copy the sections of the Owner's Manual pertaining to Maintenance of Engine when used on the track or in Competition and give them to me. Also told Service Writer that GM's practice is to approve just one repair/replacement. After that I am on my own. ....

Guy's motor popped.
They put in another one.
3500 miles later, that one pops.
Even if he is still under warranty, he just might have a helluva time getting them to put a third engine into his car.
And possibly through no fault of his own, if some debris from the old motor got into this new one.
That burden of proof, is likely to fall on him. Especially since the second motor popped on the track.

Well after reading through this I am wondering the same thing about how well the oil system and lines were flushed? I can image several different potential scenario's if that was not done. Additionally, if not flushed and inspected for debris, the problem could have just been compounded by the track time. Really hate hearing stories like this and I hope things work out for the OP.
