BigTex Posted September 13, 2003 Report Share Posted September 13, 2003 01 model is 204 211 .525 .525, 116 LSA and 2 degrees retarded 02+ model is a 204 218 .551 .555, 117.5 LSA and 2 degrees retarded I ran an 01 model in my Z71. It idles like stock, but made much more power up high. The 02 model should make more power. The only thing I don't like about these cams is the 2 degrees retard. I'd use an adjustable timing chain and advance either one 4 degrees to end up at +2. That would help the low end. Link to comment Share on other sites More sharing options...

It take off nicely but wouldn't really kick in till around 3000 plus rpms. Link to comment Share on other sites More sharing options...
BenKey Posted September 13, 2003 Report Share Posted September 13, 2003 Hey, you two above, or anybody who knows cams, what do you think about the cam shown in the link? And your opinion on the addt'l parts over to the right side? Please. I am going to get if I can find someone with the knowledge to help me install, providing you guys say it's a good one. Also, if anyone has any links on how to do this stuff, I'd appreciate direction. I've never done a cam install, but that's never stopped me and I'm not afraid to do. I figure if I had everything off to do a s-chgr install, may as well take a couple things more off and go for it. CraneCams -Ben Link to comment Share on other sites More sharing options...

I've never done a cam install, but that's never stopped me and I'm not afaid to do. Sorry I don’t have a link for a step-by-step walk through for a cam install, but here is a LINK to a nifty tool set for your first big install… Good luck Ben! But really good luck on that install, digging into that motor is going to be a big job for a first timer... Link to comment Share on other sites More sharing options...
BenKey Posted September 13, 2003 Report Share Posted September 13, 2003 Darric, LOL...that would probably cover all the tools I need, you think? But, in all seriousness, tools aren't the problem, just good 'ol fashined know how. I could do everything, bar any special tools, to take this truck down to nothing with the amount of tools I have, pnuematics and everything. That's why I want to do, need to justify their existence - more. Link to comment Share on other sites More sharing options...

BigTex Posted September 14, 2003 Report Share Posted September 14, 2003 The truck cam install is very similar to the cars. Look here for good how to info: http://www.ls1howto.com I dont recommend any Crane cams. They have lazy lobe profiles. This will hurt your low end and only make power on the top. That particular crane isn't really any larger than the stock cam we have. Look at Comp Cams catalog: http://www.compcams.com/Technical/Catalogs...-03/172-217.pdf Page 32. Look at the Xtreme RPM section, second cam. 54-412-11 This would keep your low end and really boost your upper rpms power. A good daily driver cam. If you go larger, you'll sacrifice your low end for upper rpm power. You'll also need to spin it higher. Also Page 32: Xtreme RPM High Lift, first cam: 54-424-11 Almost the same cam as above. This one has more aggressive cam lobes. This one would make a little more power while assisting low end, but increases valve train noise and shortens valve train life. BTW - I have an extra Comp cams 54-412-11 - 212 / 218 .529 lift 114 LSA with comp 915 valve springs if anyone wants it. Link to comment Share on other sites More sharing options...
BenKey Posted September 14, 2003 Report Share Posted September 14, 2003 Thanks BigTex, sent you a PM. What did you think of the 1.8 rockers that were on the page? They come with diff pushrods as well. Also, do I have to degree this cam with some type of special tools, or do I even have to? -Ben Link to comment Share on other sites More sharing options...
BigTex Posted September 14, 2003 Report Share Posted September 14, 2003 You dont need rockers if you just buy a cam with the lift you want. Rockers just increase lift. Typically, you dont have degree the cam. Just install the cam with the crank and cam gears lined up dot-to-dot. Link to comment Share on other sites More sharing options...
red64chevelle Posted September 15, 2003 Report Share Posted September 15, 2003 Does anyone know the specs for the stock cam in the SS? I just want to know how far from stock I am going. How much for the cam Tex? How much lift can you get before the pistons and valves start to get friendly? Link to comment Share on other sites More sharing options...
BigTex Posted September 15, 2003 Report Share Posted September 15, 2003 Depending on duration, you can run .600+ lift without PV problems. Stock cam is 196/207 .467 .479 lift 116 LSA Link to comment Share on other sites More sharing options...
Krambo Posted September 16, 2003 Author Report Share Posted September 16, 2003 How about this one? Camshaft Specs: Valve Lift Duration [email protected] in: .559" 267º 214º ex: .566" 275º 222º Seems a bit aggressive. Anyone think this will pass an emmission test?

Davewfo Posted October 27, 2003 Report Share Posted October 27, 2003 I know you guys have the specs for the 01 and 02 model, What about the 03 or 04 Model in the latest version of the LS 6 ? Are they the same cam as the old ones or a new grind and lift ? Also anyone that has done this has it made a big difference vs the stock setup ? Also how is the gas millage ?

BigTex Posted October 27, 2003 Report Share Posted October 27, 2003 I'm pretty sure the cam in the 02 model is used for the 03 and 04 models as well. I personally don't know of anyone who has this in their truck. Link to comment Share on other sites More sharing options...
