Can Anyone Tell Me The Specs On A Ls6 Camshaft? Like Duration, Lift And So Forth?

the 01' Z06 cam is 204/211 .515/.522 116lsa
02' Z06 is 204/218 .551/.547 117lsa

no problem

i have seen many different specs, depending on source
early versions- 204/211 525/525
later versions- 204/218 551/547 or 204/217 551/555
i have even seen later specs as high of lift as 561

I've always seen.. (02+ cam)

204/218

.551/.554

117.5 LSA

Exact specs:

02+ Z06 camshaft 0.006 0.050 0.200

Intake Duration - ID 270 204 125 02 LS6 intake
Exhaust Duration - ED 277 218 135 02 LS6 exhaust
Lobe Center Angle - LSA 117.5 117.5 117.5
Intake Centerline - ICL 120 120 120

Intake Valve opens - IVO 15 -18 -57.5 BTDC
Intake Valve closes - IVC 75 42 2.5 ABDC
Exhaust Valve Opens - EVO 73.5 44 2.5 BBDC
Exhaust Valve Closes - EVC 23.5 -6 -47.5 ATDC
Exhaust Centerline - ECL 115 115 115
Overlap 38.5 -24 -105 degrees

Notice that the cam is retarded -2.5 degrees. The ICL is actually 120. This is one of the big reasons why the '02+ LS6 cam will rev so well with such small intake duration. An intake valve closing point of 42 degrees works very well.

all the genIII/IV cams are retarded from the cam doctors i've seen.

Here's Comp's version. Bob

I'm pretty sure the shelf 212/218 .558/.563 115+0 lsa is the improved comp version of the LS6 cam. It's the exact one I chose for my stealthy turbo LR4 swap.

http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=1089&sb=2

looking at the OEM LS6 cam specs, geeze those lobes are lazy! The advertised intake duration at .006 is 270 degrees for only 204 degrees @ 0.050! The old high lift comp (which is also considered pretty lazy by today's standards) actually has less duration at .006 (265 degrees) but more at .050 (212). It also closes the intake valve quite a bit sooner (68 vs 75) so it should have a noticeably better low end and mid range when used in the smaller 4.8/5.3 engines in heavier vehicles which is often a complaint of those who have run the original style LS6 cam and are disappointed with the noticeable loss of low end power.

Looks like my link didn't work.

just google search 54-424-11 to see the cam card.

the 204/218 117.5 lsa cam is a waste of time in most cases Imo

Sorry for digging up an old thread.

Does anyone know what the actual cam valve events are for the ls6 cam.
as in.

Inlet open before tdc
Inlet close abdc
Exhaust opens atdc
Exhaust closes atdc

Thanks in advance everyone as I'm trying to work out what the factory dynamic compression ratio was set at.

Check Post #7 above. Pat Guerra knows his stuff. If he posted those specs, you can believe them.

If you read anything you would see that exact info is already in this thread, and has been since 2006.

I understand you're looking for stock specs. This is only my opinion, but if you're putting an LS6 together, as long as you've got it on the stand, I'd at least go with the upgrade cam. Not talking about a 230/240 duration@.050", with .640" lift! But a simple 215°/220°, .590"-.600" lift would make a tremendous difference with OEM 243 heads, and would idle and drive about as close to stock as you're likely to find. Again, my opinion. But if I had an LS6 going together, it sure as Hell wouldn't be with a 204° intake duration, .550" lift cam.....

BTW, I have read that the '01 LS6 cam had
207°/211° duration, .525"/.525" lift, 116 LSA. A lot of figures out there. HOWEVER, I once actually witnessed 2 Z06s run each other at the strip many years ago. They were stock, and identical, except one was an '01, and the other was an '02. Looked like twins! The '01 had 1.8 rockers, rather than stock 1.7s. Only mod either car had. I don't remember which car won. I only paid attention to mph, which is most indicative of power output. The '01 had around a 1mph higher trap speed, without exception. This somewhat verified what I'd heard up to that point, and that was if you ran 1.8s in the '01s, they ran as good as, or better than, the '02-'04. FWIW......

My Cam Motion Titan 2 in my ls6 has been awesome. Great street driving and has been shifted over 7k.

According to the Summit database the 01 LS6 cam specs are- 204/211, .525/.525, 116 LSA
After that (02 on up) it went to- 204/218, .555/.551, 117.5 LSA

I'm building a ls6 with high compression 11.67 to 1 with a suitable cam for the dynamic compression ratio.
I want to find out the factory cam valve events so I can calculate the factory dynamic compression ratio and know what to aim for.
Because too small of cam will give to much dynamic compression ratio and to big of cam will lose torque down low.

Shtstr

I have those specs but it doesn't give you actual timing events only @50.
Can be a big difference between the two depending on the ramp rate.
It could be anything.
