Blew my motor
Well it finally blew. Was having some fun with a few friends and motor blew. Not too bad since I put about 3K supercharged miles and 9 gals of methanol through my stock internals LS7. I'm suprised it lasted this long. Anyway I'll be down about a month. Car is at Taylors (Dallas Performance) now, lots of metal including pieces of spring came out of the oil. I had Taylor order me a badass LSX 434 shortblock for tons of boost. Keep on the lookout for my build updates. Should be interesting.
This is not a bash LS7 thread either, I beat the hell out of the car when I drove it, I had 9psi, big cam and methanol. The car put down 770rwhp/667rwtq so it was a matter of time. Now I get to make it faster

But if you really think it was about time it blew. And suspected it was going to blow? Why on earth would you not just pull the engine. Swap in the new one.
Since it WAS worth alot more than the Scrap Value it is worth now!
You still could have made it faster with more money and less expense.

There are a lot of boosted Ls-7's. Very little failure.The ls-7 likes boost! Don't blame it on the engine! Some people can blow up or ruin ANYTHING!
No telling, what the tune was. How the driving was? What gas was in it?
I have caught the gas attendant trying to put 87 in before. I watch
everytime. Yes they by law must fill the gas here. You get get fined for touching the pump.
The blind statement like that doesn't fit all!

I have close to 25k on my A&A kit. About 7k of that on my Ls-7. I don't plan blowing my engine, but I don't beat the snot out of it. But it gets a sprirted romp now and then. It has no meth 8psi and about 100 rwhp less than your numbers.

They always blow, sooner or later; heck even a bone stock engine has a very finite lifetime; what's the big surprise that it only lasts 10k when making nearly double what it was designed to do?
Good luck with the new build. I want to do a boosted Z06 next but I'm not sure I can get it to last even at low boost with the way I drive :-/

Good luck with the new build! Except with proper care ANDdriven correctly a stock motor is good for 300,000! I put 125,000
on a LS-1 and some else drove it for years after that. One of my fleet has 208,000 and still runs great. I'd say more like stock they are hard to wear out. Most sell them first.
