I have decided to possibly go with a smaller cam than the T1 (probably going to sell- haven't installed yet). I was thinking about going with an LS6 cam. What are the specs on this cam? I have new 918 valve springs ready to go in. What kind of pushrods should I get. Will this cam be a lot "easier" on my motor than other cams (T1, TR220, TR224?) And lastly, how will it perform compared to the GM hotcam? Thanks.

I have a cam for sale that is a little different than the LS6 cam. It is a TPIS ZL10 cam.

208/216 525/525 116lsa I am selling for $100

What are the specs to an LS6 cam? I might be interested.

any info?

Wouldn't it be a bad idea to run the '02 LS6 cam on a LS1 since it has a smaller base circle...and GM had to lengthen the valves on the LS6??? It seems it would be better for my motor if I buy the '01 LS6 cam..??

i posted the same question as u a couple of days ago, it should still be on here if u just look through the past post, all the specs are on it.

ttt...I don't want to risk breaking valve springs....so should I go with the '01 LS6?

01 LS6 cam: 525 525 204 218 116
02 LS6 cam: 550 550 204 217 117.5
hotcam : 525 525 218 227 112

I gained 11 RWHP on the car with basic bolt ons and the 01 LS6 cam.
I gained 7 RWHP with the hotcam and the same bolt ons.
Both cams made the curve better on the high end.
The hotcam even more so. Both cams require better valve springs. The 01 LS6 springs. They come with the hotcam.

I just put in the 02 LS6 cam and stage III heads.
I didn't gain anything, But that is because I'm maxing out the s/c. A long story I won't go into here. But All I put in was the cam and The 02 LS6 Springs. No pushrods. The 02 LS6 valves are longer because the chamber on the 02 LS6 heads is not as deep(more chamber material). Thats why the 02 LS6 compression ratio is 10.8:1.
I believe the 15-20 RWHP gain. Plus the curve will be better. The spings should cost you about $85.

Hope this answers some of your questions.

Who sells the LS6 cam? The dealership said it was 313 dollars!!! WTF? And they said it was about 10 dollars per LS6 spring!

I just pulled this off of the Scoggin-Dickey (SDPC) web site:

P/N 12565308, 2002 LS6 Hydraulic Roller Camshaft, $185.00 (sure beats the $313.00 you were quoted)
____________________________________

P/N 26918-16, Comp Cams LS1 High Load Valve Springs, $154.95, You will need these "drop-in" replacement springs due to the fast ramp speeds of the LS6 cam. These are a better spring than the GM LS6 springs you checked into. Use your stock retainers.
____________________________________

The 2002 LS6 cam will also require a set of 7.45" hardened pushrods. (.050" longer than stock)

Here's an interesting tidbit for you...................

.7mm = .02756"
1/2 of that....the radius = .01378

stock pushrod length is 7.40"

The ideal size with the '02 LS6 cam would be 7.41378"

Most TR cams have a base circle that is .030" smaller than stock. That's a
radius of .015", making the ideal pushrod 7.415".

There is no need for you to change your pushrod length <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> You'll be better off
with your current pushrods and the '02 LS6 cam than you would be with the TR224 and 7.40" pushrods.

IMO

Consider the 02 LS6 cam as it has more potential than the 01 LS6 cam. I am not a fan of the 01 LS6 cam as it requires a lot of work for a small gain.

Here's a little more info on two of Comps Cams other to think about too:

Comp Cams has a 216/220, that is a nice cam that isn't over kill. Thunder Racing shows just over 400+rwhp with this cam and Stage I heads!

216 / 220 .525 / .532 114 LSA 1300-6300 RPM Power Band. Computer Tuning Required with automatic transmission cars. One of our most popular cams...This has proven to be a very well balanced camshaft in that it makes good power across the entire RPM range. Works well with Crane 1.8 Roller Rockers.

212 / 218 .522 / .529 114 LSA 1200-6000 RPM Power Band. Excellent low-end power. Mild Camshaft, great for automatic cars with the stock or mild aftermarket torque converter and daily drivers.

I think the 212/218 on fast ramps (XE) might be decent in a mild application too.

If your worried about springs the REV-1116 dual springs might help. They don't require machining the heads.

we've seen 20rwhp and 19 rwtq on 01 m6's with the 02 cam and springs

Your calculations are a little skewed.

The stock LS1 cam has a 'base circle' of 1.552" (across the lobe)
Thats equals .775" (exactly 19.7mm) from 'cam centerline' to 'lobe heal'. In fact, GM states that it is 19.7mm

GM states that the 2002 LS6 cam has a 'cam centerline' to 'lobe heal' distance of 19.0mm
That is exactly .748"

The simple math will tell you that the difference in 'cam centerline' to 'lobe heal' distance between the two cams is .027"
To be exact, the LS6 cam would require a .027" longer pushrod than the LS1 cam.

Although GM uses the term "Base Circle" when it states that the LS1 is 19.7mm and the LS6 is 19.0mm, they are talking 'cam centerline' to 'lobe heal' measurments. There is no way in hell that those measurements are "across the lobe".

What you are doing is taking the .7mm difference between the two cams, and then cutting that number in half. You can't cut the number in half because we are talking .7mm difference in the cams centerline out to the back of the lobe heal. [Not] a difference of .7mm across the lobe (base circle). GM may have used the term "base circle", but I can tell you thats not what they meant. There is [no] chevy cam with that small a measurment [across] the lobe....

Get a mic and measure your standard LS1 cam yourself. You will see. Its 1.552" across the lobe.

Not trying to be argumentative, just hope you understand what I am saying here.

Ron,

I think that either of the choices cited by Black Bird T/A would be a bit better than the LS6 cams.
You will still have a smooth idle but the tighter LSA will give you better midrange and the higher durations a bit better top end.

I like my 218 single pattern a lot too. Other mods and results of my "old man" setup below.

Ron,

Thanks for pointing that out. But even at .027" longer than stock, that is a pushrod length of 7.427", making the 7.40" length pushrod the best choice. You could go with a 7.45" pushrod, but I'd rather go on the slightly shorter side and let the lifter soak up the difference. I will be installing this cam Friday into an '02 SS, and we'll see how it turns out.

My cam is up for sale if anyone is looking for a surge/trouble free cam. No crazy ramp speeds to break the valve train.. stock idle speed.. I was actually running the stock springs with it for a few weeks, even at the track.. I wouldn`t recommend doing that for long thou.. I was just waiting on new springs <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
