I personally know a guy with stock ls3 internals pushing over 800whp and has been for awhile. He owns a shop in Houston called Auto Adrenaline and he is the tuner. He claims the ls3's rods and pistons can hold 1000hp.
Speedo videos please! And maybe a write-upAfter I'm done with my swap, I will tally up the cost of my swap and I'm positive it will be less than the cost of a blower. At present time, I'm hovering around $2500(This includes selling my 4.6L 3V/5-speed combo)...and I've got all I need, save for a few small things (oil, belt, coolant, CAI, etc.)

well he is wrong. i know of several 550-600rwhp LS3's in vettes and camaros that have crapped.
1000hp? he needs to let folks who have blown them up at 475rwhp know that.
Here is a run @ 752whp. Since then he has upped the boost and is using E85 and making 840whp... Still up and running, he is a bad ass tuner. I am sure those other guys that break at 475whp will cry when they watch this
He also says that he has tuned other vettes and camaros making 650+ all day and a few others at the same power level as him. All stock internals.
^ Lol he will always be right?? Whatever guy I just showed proof of one of many that hold up. Let me see one break on the dyno with 475whp. You don't have to be jealous it's gonna be ok bro
I am sure the weak ones that break are being tuned by fuck heads
i was being sarcastic... if you read back through my post, you'll see where i actually said all the same things you have said

I had a cam/tune on mine.. yours went through the pan, mine went through the block, you might be able to reuse your block.. i had to get a new motor.. lsx376.
but you might have seen my posts on here about that.
i'm sorry. it's sad to see things blow up.. when you take the top apart, look for a failed lifter like mine..caused the valve to hit the piston and go kaboom.
Moorepheus said:All these modded Camaro dying. Maybe these engines were not designed to be modded at all. I mean, every other day, we are hearing about these modded Comaros dying. Don't get me wrong, I have nothing against modding, I don't do it personally myself, it is just an observation.
Just wonder, anyone have same thing happen to themselves in an UNMODDED Camaro?
Good luck with fixing it, hope you are on the road soon.
Took out a Porsche 911 turbo the other day. About an hour later, my shortblock let go. Looks like it is a rod or rod bolt, but not postive.
