Had to pull my 2004 A&A S/C'd Z06 apart because I had a front balancer seal leak. Since I have it down to this, I am going to throw a stage 2 A&A blower cam in and and freshen some stuff up. I am guessing the car will want to make over 600rwhp easy. It will be street driven for the most part. Car will be used for straight line pulls (at the strip) and driving around town. Have some questions though....
1. Should I replace the timing chain? LS2? Double Roller? And do I need a timing chain dampener (where would I even buy this)?
2. I have 45k on my car, I am going to go ahead and freshen up the oil pump while I am in there. Is the ported LS6 pump from Texas Speed the way to go? Or is there a better deal in town with the same oil pumping performance?
3. Is there anything else you can think of that I might want to do?
I am running a ls2 chain with the texas speed ported pump and a chain dampener from katech performance in my ls6 powered 85 c10. Havent had a issue yet.
I used a Roll Master single row chain in my FRC it tightened up things and no chain dampener was needed. I tried the LS2 chain first, it made no since to me to install one that loose. I also installed a new melling oil pump, I ported it myself, there are procedures out there to do this and it in not difficult at all. I've used Roll Master timing sets before they are quality parts.

Did you have to modify the timing chain cover or anything to get the double roller setup to fit?
Cloyes Hex-A-Just comes with the good LS2 chain and billet sprockets. It's tight so you won't need a chain dampener and it makes it easy to dial in your cam.

+1 but I would toss that Ls2 chain and replace it with the C5R chain from Katech. It's pricey but the difference in beefiness is noticeable when you put it side by side with the Ls2 chain.
My C5R chain was VERY tight on the hex-a-just set but I went ahead and added the damper too just to be extra safe. I was lucky that my block was pre-drilled/tapped at the factory.
After reading a LS1tech thread about the C5R chain, it seems to be hit and miss. They seem to break sometimes just like the rest of the chains on the market.
Could it be that people are going double roller because you have to lose twice to lose it all? Instead of with a single chain, lose once, lose it all.
Thanks for the help guys, keep it coming. Seems like this timing chain thing is one of the toughest un agreed upon issues in the LSX
community.

Could you post a link to that thread?
I hadn't seen any instances of the actual Katech C5R chain failing, and I'm gathering parts for a cam swap...timing chain is on the list.
i have a 02 z06 that i just got got back from east texas muscle
so to answer a few of your question for one i would not trust my vette to anyone but stephen
he did suggest that we put a high velocity oil pump in it and timing chain.. the mods that i had done were cam,rods,springs,k/n cold air intake, longtubes and we ordered the 2.5 heads for it today
i want to keep the car naturally aspirated i like the sound of the cam myself it runs pretty good now cant wait to get the heads on it
anywat i had 45,000 on mine
east texas muscle cars .com it will be worth your time to give him a call

I have seemed to have lost it, but it was a very good thread on this subject. If I find it again (I need to) I will make sure to post it. They also discussed how tough the C5R chain was, but that Cloyes top chain was stronger. I guess someone, or Cloyes, spent time comparing the two.

thanks for the props man!
to the OP
i would put a chain in it. even if you only go with the ls2. 45K isnt a ton of miles but we have seen the chains start to get slack in them by then, and to do the chain you have to pull the pump so might as well put a good one in there.
Mine is a single roller, I ordered a Katech chain from Texas Speed and when I put it on it too was loose just like the LS2 chain. I called them and they were aware of the issue and were more than glad to refund my money and then sell me the Roll Master chain. I know others will challenge this but I'm satisfied with the Roll Master. I guess any chain is good as the next until it breaks.
