I have an 02 Z06 w/ 54k miles on it. I messed up and didn't change out the timing chain when I did the cam. Anyone know how long the stock one is good for? the mechanic that worked on the car said that is was still nice and tight and didn't need to be replaced. any ideas on this?

You didn't mess up at all. Don't sweat it.

What valve springs? The issue as I see it is you have a 54K timing chain with likely heavier valve springs and a more aggressive cam profile so the chain is going to see more load. Any plans on future mods that would allow you to change it like an UD pulley or something. Personally, I wouldn't feel comfortable.

Matter's on the Cam lobe and springs used.I've seen alot of stock chains break but also alot of people say there's lasted.

I personally would never do a Cam without a chain upgrade- Mostly LS2 or doubles.

Crane makes a nice timing chain, its a cnc pro series steel billet double row timing chain. Its around 210

Thanks guys, just what I'd hear. I do have a pretty big cam, and the prc double spring set, so I'm sure I'm putting a nice load on it. I'll probably do an under drive pulley here in the near future. I'll look into changing it then.
Thanks.

Yeah an upgrade wont hurt. You may or may not break it. You are definitely making some power surge through it though! I bet you have 500+ off the crank.

That is a pretty pricey chain for doing the same thing that most other half that price chains do...The LS2 is all he really needs. Double rollers are nothing but a pain in the ***. Plus it will save him 170 dollars going the LS2 route.

I have a IWIS chain that I got from Thunder Racing, 150 bucks for that thing, but I heard it was a good chain. I got a kick out of the "For offroad use only" sticker that was on the bag the chain came in.

I ran my stock one....well from the new motor with 5k on it..and its fine. Then again, I dont really have a huge cam either....

I think I'm just going to get the LS2 chain, it should work fine on the stock sprockets, right?
