Hey all:
I have just a little over 14,500 miles on my 02 Z-28 and going to install a new tr224 cam, springs and pushrods. Should I go ahead and install a new single roller timing chain or even a double roller timing chain?
Also what benifit's is there to the double roller timing chain?
Thanks all Ken

Also any benifit's to install a titanium retainers?.

Also any thing else I should consider changing while I am this far?

if you are going to open the car up in a few more years then no, dont get the chain. but if you are planning to never change cams, etc then get the timing set- its good insurance.

titanium is lighter. the lighter the valvetrain the better.

as far as the titanium and pushrods etc. i would get it if i was never planning to open the car up again, but if you have more plans for the future then go ahead

I'm sure if you are putting a tr224, you'll change springs, so get 7.40 hardened pushrods while you are at it. And if you get Comp 918 springs, no need to change the retainers unless you really feel like it.
I think TR has a cam with 918 package to give a price break.

I had the extact setup PREDATOR-Z is talking about. I ran it with the 918's and the stock chain with no problems.

I also ran the TR224 same setup, too small . I would get the Ti retainers, hardened pushrods and no on the chain. IMHO if your stock chain isnt stretched yet, I wouldnt replace it, havent seen to many, actually any, reports of chain breakage. Its more of a POM thing. I would not go to a dbl roller at all with a hyd roller setup, maybe a solid roller. I will be installing a Cloyes/JWISS single roller adjustable soon, more for the benefit of dialing in the cam, nothing else. As is, my stock timing set is still on my car, after the stock cam/TR224 and now TSP 231/237 cam, still in acceptable limits of strech w/ no signs of abnormal wear on the gear set over 33,000 mi w/ over 600 1/4mi passes and lots of nitrous. But thats just my HO.

The chain is more of an insurance policy and if double adj. roller the chance to adj. timing up or down by a few degress. This might by useful- in the future if you like the cam, but want power peak soon(lower) or higher (later) this adjustability might be useful, but not necessary. You really need to check the condition on the chain, very, very few break..
The retainers are really to help lighten you valve train to help in abit more rev's or more stability- Yes to the pushrod's, 918 good, but 921 even better. What lift will you see with this cam?
