What are the stock cam specs of the '05 LS2 cam?

Would you expect any issues if this cam was put in an LQ9 motor with respect to the cam sensor?

Thanks....

It's the same spec as the 2001 LS6 cam. 204/211 .525 lift 116.5 lsa, but does not have the reluctor ring pressed in. So just order the actual 01 LS6 cam so it has the reluctor ring for the cam sensor pressed on and you're good to go.

So are you saying that the LS2 cam does not have a reluctor ring at all? Or just the wrong/different one?

I have an '04 Denali too....but it's not stock They are great!!

I havent actually seen a LS2 cam to verify it, but I think it's safe to assume it does not have a reluctor ring because the cam sensor signal is picked up from the front timing cover.

BTW - What mods to the Denali?

No ring on the LS2 cam... got one in a voodoo box out in the shop.
Just don't know what to do with it.

You'ld be better off ordering up the the 02/03 LS6 cam. Slightly larger and if you happen to have a set of LS2 (243 casting) heads they should already have the GM yellow springs installed. The ones that can handle up to .550 lift.

Yep, that must be it and why when the engine is running and I clear the code it comes right back! I swapped the springs when I did the cam so I have the yellow ones in there now.

I need to go back to my buddies speed shop and trade the LS2 for an LS6 cam it looks like!

Thanks!

Are you saying the 03/02 LS6 cam has slightly larger specs than the 05 LS2 cam?

Yes. The 02-04 LS6 cam has more exhaust duration (218 vs 211) and slightly more lift at .551/.555. You need to switch to the different springs as well.

Well I guess the only thing is that if I go to an '02-'04 LS6 cam I will have to change the springs again so they will handle the lift . The yellows are only good to .550m I wonder if it would be OK at .555 ?? That's not much I would think. I was hoping to just swap the cam and leave the spings alone this time, I HATE retainer locks!!!! They are the root of all evil Though I only dropped one this time

DrkPhx, this LS2 cam is in my Denali along with an AirAid intake feeding a Magnacharger with a 2.85 pulley pushing 9+lbs of boost exiting through a B&B triflow catback exhaust with an upcoming custome tune. Untuned, I whipped an intake and exhaust modded 350Z from a dig over the weekend.

Stock LQ9 cam: 201/196 .479 .467 116 LSA
Stock '01-02 LS6 also '04-'05 LS2: 204/211 .525 .525 116.5 LSA
Stock '03-'04 LS6: 204/218 .551 .547 116 LSA

Everyone agree with these specs and years?

Stock '01 LS6 also '04-'05 LS2: 204/211 .525 .525 116.5 LSA
Stock '02-'04 LS6: 204/218 .551 .547 116 LSA

Just a minor correction...02 - 04 (vice 03-04) LS6 had same cam. This is one of the reason why 2001 Z06 came with 385 hp and 2002 - 2004 Z06 had 405 hp rating.

The yellow springs are the 02-up LS6 cam, so you are okay. Sorry, didn't realize you had those springs.

I would love to put a supercharger on my Denali. Do you have a soundclip of the exhaust? Curious to know how loud it is on the inside when driving.

According to our cam doctor, the LS2 specs are as follows.

Lobe Seperation = 115.9

Intake Centerline = 111.9
Exhaust Centerline = 119.9

Intake Duration @ .050 = 203.7
Exhaust Duration @ .050 = 212.5

Intake valve lift = .52044
Exhaust valve lift = .52111

What's the part number for the 01 z06 cam? Also is the '01 z06 cam physically smaller than the '02 or does it still need the 7.400 pushrods?

TrueBlueGTO

Nevermind...read the article on the z06. Just to make sure I understand. I won't have any "interference" problems with installing the '01 Z06 cam with '02 Z06 valves right?
