Thanks for the reply. Well that answers one question. I do not have an LS6 cam. I can be an idiot some times. I should have asked for positive verification before buying. As soon as I got it I smelled something fishy so I checked lift by measuring the difference between the longest dimension and the base circle. It doesn't appear close to something in the 0.550" range.
That brings up the other part of the question. Now that I know it's not an LS6 cam, what cam did I buy? Anyone know?
Just because your numbers don't match the numbers of the 02 LS6 CAM doesn't mean that you don't have an LS6 cam. I was looking for a picture of the LS6 cam I had from an 04 ZO6 but couldn't find. Before you completely dismiss your cam as being a LS6 cam do a little more research. Try Goggling the numbers.

.550" is the lift at the valve taking into consideration the 1.7 rocker arm ratio.

I measured the longest portion of the lobes, subtracted the base circle dimension, and multiplied by 1.7. I'm coming up with something in the .530" range. I may be off a little bit but it's looking like an '01 LS6 cam lift to me. Isn't the lift somewhere in the high .520s range for an '01 LS6?
I tend to believe it's a GM cam since the numbering format is the same as an LS1 and LS6 cam. Is there a chart somewhere that lists all the GM cams so I can track down this part number?
OK...Let's assume I have an '01 LS6 cam. Should I use it or buy an '02+ cam? I'm putting an '00 LS1 in a Factory Five GTM but I'm going with LS6 heads, intake, mass air, and cam on the LS1 engine. I'm looking for a very street friendly build with a little more power than the stock LS1. Just looking at the cam specs for both cams it seems that the '01 LS6 cam will give me torque lower in the RPM band but not as much overall power as the '02+ LS6 cam. Right? If that's the case, it's not such a bad thing for a street car. Having said that, I'm not sure that I'll even notice the difference unless I go to the strip which I don't plan to do with this car. Also, I do not plan to increase the rev limit beyond what's already programed for a stock LS1 so that may reinforce my thinking that that the '01 LS6 cam is OK. What do you think?
Do a Google search for Hib Halverson's "The Relentless pursuit of Power". There are two articles, the first for the '01 and the 2nd "the sequel" for the '02. Plenty of cam info and dyno charts, etc.

If you are willing to sacrifice a little power on the top end, the 01 cam will give you increased valve train reliability.
The cam listed below will give you a very noticable tq improvement over the ls6 cam. Idles like stock, pulls from idle, and doesn't need any rpm to perform, like much larger cams. I don't remember the actual numbers, but it's probably 15-20 ft. lbs. more torque over the LS6 measured at the wheels. There are also cams from other mfgs with similar specs. I simply have experience with this one. http://tpis.com/parts/view/102

How does it achieve the increased torque? It has less intake and exhaust duration than the LS6 cam.

Yea I wouldnt worry about the lift difference too much. Its still a great cam. I'm pretty sure they used the same specs for the ls2 engine, didnt they?
Actually, if you really want the new LS6 cam, mine is just sitting on the shelf in my garage. I pulled it out of my 03 Z in december with 26k miles on it. I'll give it to ya for $70 shipped.

hmm now I'm baffled. I've done some research and with most cams you simply put those top 4 digits at the end of the part number. So for my cam from my 03 Z06:
5308
S 15
2228
I did the same thing and came up with the same result. An LS2 valve. What the?????
What's going on here? What the heck cam do I have? Based on the format of the numbers I'm real sure it's a GM cam but I'll be damned if I can figure out which one.
