Stock Bottom End 04 Z06. 9.04 in 5000' DA 
Sad thing is she let go about the 1000' mark. I have beat the **** out of this motor for 11 years so I can honestly say it doesn't owe me a damn thing. went from bolt ons, cam, head/cam, heads/cam/spray, and finally heads/cam/blower. this is also a heavy car. i would say around 3700 with me in it.

Wasnt there a run of LS6 engines that had valve spring failures causing the engines to fail?
THis is what a friend of mine told me right after he bought his 03 Z06. First thing he did was buy a set of valvesprings from Tooley.

Yes, the 02-03 yellow valve springs sucked.. They were time bombs.
That's not what caused this failure.. 850rwhp unlocked after a bunch of passes did. My guess is a piston came completely apart.
Car is about 3600lbs raceweight. Blower kit and supporting mods, auto swap with heavy drivetrain stuff, full stereo system and a 200lb driver.
