My C6Z06 is down... 38,000 miles, 2006 C6 Z06, I broke a valve spring leaving the track last Sunday. I was at 1800RPMS in 6th, on the highway and I felt it give out. I killed the engine and towed it home. Popped off the old valve cover to find this:
I heard word today that the Piston is okay, I have decided to leave the bottom end alone and spend that "money" towards a new block.
SO, heads and cam for now!
GAME ON!
Look for my 200ft drift after the warm up lap, notice the cars on slicks, once they get to operating temp, they are FAST. I also force a 7k downshift following a buddy into a corner at his speed, which did not help the valve spring

Car made 494/474 before internals.
Heads + Cam + FAST102 + Fuel system = ___ / ___
BTW, thanks Patrick G for specing out my cam, I look forward to hearing this bad boy!

Anyways, I don't need 620 for this car, it needs full throttle at corner exit!
550 will do just fine, ****, 500 was awesome!
Yeah tore my clutch up at the track few weeks ago......I didnt break a valvespring but i need heads fast intake and throttle too haha.....Hoping for 600 to the wheels! Let us know what you put down!
I can see why you broke a valve spring after watching the first vid.
Sounds like the motor was mechanically over revved a couple times during those down shifts going into the turns.

I'm putting 551 with a cam and fast 102 and headers through an auto. We think it's about 680 at the crank due to the loss in the auto tranny.
Cam, heads, headers, intake 620 rwhp is pretty easy on these bad boys.

It was a combo of 38k miles, ME and the downshifting which killed it.
It did NOT break until later in the day, I drove the car many times after I over revved it and it was fine.
O WELL, things happen for a reason, more power here we come!
there are lots of cam cars doing that with the 427. Its not hard.

Yeah you can hit it but you have to use a mostrosatus cam....I used to want to hit a big whp number, i just dont wanna sacrafice that mid range power....Solid 590 wheel with a good mid range in a c6z is a fast sob...The lingenfelter cam they are using for these big numbers (i think gt-22) is over 670 lift(The springs themselves are 800 bucks) Just seems like it would be a turd out the hole and you would have to launce it way to hard at the track.....
I was totally happy 500, my smile is about to grow!!! WooHooo
Hope you get the motor back together and out on the track for some more racing.
