I have a 99z and I'm doing a cam install, should I replace stock timing chain w/ aftermaket? which one? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

You don't have to, but you might as well while you're in there just to be safe.

Here's the double row timing chain:

Or you can get the JWIS chain from thunder racing, its a single and is built nicer than the stock one. Doesn't require oil pump shims or potential underdrive pulley interference like the double chain.

 

what mods if any do you have to do to use an SLP timing chain? I was thinking of buying

 

If you can't get it from Thunder, I got my JWIS chain from katech. Part number G68VC-60 and it was ~ 110. shipped.

What is JWIS? who makes it? is the timing chain from sdpc pretty good, only $85!, better than the SLP timing chain?

 

Get the Rollmaster Double Roller from SDPC, thats the best deal.

 

rollmaster billet single fron SDPC much better than stock and no fit or shimming problems.

 

got a link to the rollmaster single billet from sdpc?

I just installed the Rollmaster hardened double roller. I did have one small problem. I had to run a .250 diameter drill through the cam pin hole. The hole in the Rollmaster was .004 smaller than in the factory and the pin would not go in. Other than that it fits and works great. The spacers are not a problem. I did use a small dab of high temperature sealant on the drivers side spacer.

I advanced my 218/218 Comp cam 6 degrees. It pulls all the way to 6000 rpm now and makes more bottom end torque. I'm anxious to get it to the track and see if my 60' and times have improved.

Be sure you understand how to advance or retard or you will be in for trouble.

 

Yeah, the cam pin was a little tight, but I was able to push it on with my hands, after I oiled up the pin. The double roller is a very stout piece.

 

Larry, doesn't the Comp 212/218 already have 4 degrees ground in? Did you advance it 6 more, or 2 more for 6 degrees total?

My cam card says 114 intake centerline with a 114 LSA.

I actually lost 60' with this cam installed straight up. My 60' went up from 1.58 to 1.65 range. My mph and et did improve slightly but should do even better with my 60' back. I have a 3600 stall and which was too tight with this cam and zero advance.

 

My cam was a custom cam. I bought it used or would never had ordered it with 114 ICL.

 

Interesting - The comp site lists the 212/218 as having 2 degrees ground in. Well, it says has a 112 ICL with a 114 LSA.

Just for your info: The TR220 cams have 4 degrees advance ground in.

If you are changing cams, at least install a new chain.

I used the Rollmaster [single] timing set, but it's not adjustable. I installed the cam dot-to-dot.

 

Double chain = double piece of mind! You won't break that sucker!! <img border="0" alt="[evil]" title="" src="graemlins/gr_devil.gif" />

 

I run the Katech replacement chain.Much more stout than the stocker.
Here is my reasoningouble row is stronger but adds the chance of oil leaks around the oil pump(added spacers)and an ASP pulley might contact the pump.And since I run 918's there is not much stress on the chain compared to dual spring setups.

On the Cam,I witnessed a board member do the same thing.Put the cam from 4 degree's advanced to 6 degree's advanced and he said he felt a big difference.But we went to the dyno and he gained 20hp down low up to 5000rpm then dived at 5500,but lost 35hp off his peak 6200 His is something like a 221/221 on 112 .580 lift I think,custom grind.
