hey guys, fairly new to ls1 tech. question about ls6 cam do i need to install new springs retainers and push rods with this mild upgrade in cam install. its an 02 ss A4 thanks for the input.

You will need new springs. Other stuff are optional but good ideas

meSSman02

what kind of horsepower do you see with this cam?

Most people get around 23rwhp from a ls6 cam. Wont get any below 4k but it really produces 5k and up. You need to bump up the shift points to around 6400rpm or so. You wont need a tune and the idle will sound stock. If you dont have a high stall converter get one.

I thought 02 fbodies had the LS6 springs?

As for peak power ~23rwhp, but the real story is area under the curve. JMX posted a dyno graph of an LS1 cam to LS6 cam swap. The LS6 cam gainged ~50rwhp over the LS1 cam around 6,200 rpm.

I'll see if I can find the graph

Here's the thread but dyno graph isn't hosted any more.

I remember the graph but I think the stock hp curve was just on top of and adjacent to one of the grids in the graph and people mistakenly compared ls6 hp curve to the torque curve of one of the cams.

Hi,
The stock retainers & pushrods are the same parts for LS1 or LS6.

While I spoke from memory I did save a copy of the graph...I went back and looked up the following...

3200 to 4300 LS1 cam is ~3 to 5rwhp better
4300 to 4800 LS1 & LS6 are equal
4800+ LS6 is up to 40+rwhp better

rpm--LS1--LS6


4800--285--285
5000--295--300
5200--298--310
5400--295--315
5600--290--320
5800--285--321
5900--280--320
6000--???---320

Note the LS6 cam is 40rwhp over the LS1 cam at ~5900 rpm. I the mtor was spun even higher the LS1 cam would countinue to drop off much faster as the LS6 holds even or drops much slower. By ~6,300 to 6,500 rpm the LS6 will likely have ~50rwhp edge. Etc

The graph is a little hard to read.

BTW - Props to JMX otherwise we'd not have the graph to discuss.

Here is another one.

You're right 99ta, if you calculate hp from the better visible torque curve it goes exactly like you've highlited in the pic. I was earlier looking at the grid between 5.8 and 6 k at 300 hp.

Sorry, for buttin in but i am thinking about using this cam in my 2002 z28. I am wondering about what kind of torque #`s with the zo6 cam. any info would be great. thanks.

Click on the attached image to see the dyno graph. It has the torque and hp on it. It's in the box labeled attachment above.

Not trying to hijack, but..

If you are not in a hurry, I'll have an LS6 cam and springs for sale in late Jan/early Feb. My new shortblock will hopefully be done and in by then. They have about 6k miles on them.

I'll be asking $150 + shipping. PM me if you are interested.

I compared my stock dyno (GMAF, lid) to my 02 LS6 cam chart ( 02 LS6 cam, LS6 intake, MAC's with ORY,Hooker cat-back, FTRA,LS1edit tuned, Yank Y3200 TC) and the peak was 290 rwhp at 5400 rpms to 348 rwhp at 6000 rpms. But; 6000 rpms and above is where the big difference is. The stock dyno only goes to 6200 rpms which is 274 rwhp. The LS6 cam dyno is 344 rwhp at 6200 rpms and 342 rwhp at 6500 rpms.

Obviously the headers, intake and cat-back added hp, but the cam really pushed up the powerband in rpms, but more importantly kept it flat from 6000 rpms to 6500 rpms.

I feel the LS6 cam is the best stealth cam (especially for entry level) out there when you take in consideration ultra low cost, a true plug and play cam, no tuning or idle issues, no spring issues. There are other stealth cams that make more power, but as soon as you throw the price in the equation, the LS6 cam still is the best overall one.

the ls6 cam should be called ls1-vtec; my dyno before its install was 306 hp and 308 tq on a mustang dyno. After its install, the Z put down 357 hp and only 306 tq on the same dyno. The graph had a huge pike from 5500 to 6200 rpm; I'll try to post it up later, but I regret not going with another cam that has more meat in the curve.

mmm...I think the LPE GT2-3 is an equal contender for the best stealth cam title too.

BTW did the 02 cars come with the LS6 springs?
