Hey all. Im in the process of changing the springs, lifters, and pushrods in my Z due to the common tick noise, mine is really quite loud. I have 50000 miles on the car and am curious as to the strength and longevity of the timing chain. I have heard of them breaking from repeated high rpm (7000) abuse, I dont even hit the rev limiter. So would it be worth the extra maintenance to change the T chain? thanks

If you changing that much why not spend the extra few $$$ and upgrade the chain & sprockets?

Here is my original & the Dual upgrade I did when I changed cam/lifters/pushrods/etc.

If the motor is apart, I highly recommend replacing the chain with either a heavy duty chain with dampner, or even better, the double chain shown above. :cheers:

dosent the double roller require a crank spacer and oil pump spacers? Sub driver since you run in scca you have to run the stock timing chain correct?

Correct. In SCCA T1 class we have to use stock parts unless a specific exclusion exists in the rules such as we have for wheels, oil cooler, brake ducts, etc. There is no exclusion for timing chain. However, backdating is allowed, so using an 04 part on my 02 Z06 is legal. I now have an 04 crate motor in my car so I'm hoping I do have a heavier duty timing chain and the dampner that sits in the V of the timing chain. :cheers:

I couldn't believe how cheap the stock timing chain is! :mah: Replaced it with a Thunder Racing dual roller when adding the cam and upgraded valve train goodies. :yeadog:
