Not true for us. We are working on a new style ls hot cam. So we know what its like to "aim for mediocrity" so to speak. Our attention to detail seems to be what is needed.

If you saw the difference in the 01 to 02 tune youd see what would have helped. A little timing would have picked it up. I dont think they spend all day tuning and tweaking to wring out all the power. A few hot runs and thats it, esp for a magazine test.

 

I like you guys' approach on this. There is so much said on these boards about BALANCE; A nicely ported(NOT hogged out) head, a decently spec'ed cam(NO shake'n'bake), and an intake large enough to feed the whole works (NO 55gal plenum). Surprising how much performance one can get from such a setup.
I also live in Cali, so know first-hand what limitations exist here. Not as much fun, but things are still doable with some effort in the right places.

 

Again contact Kip @ Cam motion. The 216/220 116 stage 3 factory performance cam would give a solid 45-50hp gain at the crank and drive like stock, pass emissions, and easy on springs. They can also build you a cam to suit your needs.

 

I went with the 2004 Z06 cam GMPP and am Very happy with it.

 

I think the only reasons a lopey cam would fail smog is, 1) ANY audible lope will alert the tester letting him know something's NOT stock, and 2) said lope, being a miss of sorts, would cause a sniffer fail due to unburned fuel/air.
I would think a smooth-idling cam is burning clean enough to not raise any flags, and therefore PASS. My .02....

 

The sniffer isnt just about unburnt hydrocarbons

 

Nope, CO too, and usually NOX....

 

The 212/218 cam ...... milk n cookies!! Its been proven on the dyno plus the REAL WORLD!!

 

Then again, they describe this cam as having "noticeable idle, with a little loss in low end torque", which is not what I am looking for. It is also a sign that this cam may not pass a sniffer test.

Then again, which one? Comp has a couple in the form of the XR265HR, one with more lift and a greater lobe separation than the other. Cam motion has one. And I'm sure there are others out there. It is just VERY hard to feel good about plunking down around $400 for a cam (and more for associated hardware like springs) that I may not like, especially after reading comments like this about the XR265HR:

 

-14 degrees of overlap will pass with ease...and with stock manifolds it would be stealth. However you seem to know it all so I will bow out of this discussion.

 

^^^^^He's right!^^^^^^

 

My only issue with the Cam Motion cams is their lift on the mild grinds is .55X That is back to the 2002 LS6 in terms of lift. If using 243s head stock or ported then there is gains to be had with using more lift.

I see they have a 218/222 with .586/.578. Too bad not available on a wider centerline.

Even the now old and gentle GT2-3 has .571/.578.

 

Texas speed has a stg3 truck high lift cam that is a 216/220 .600/.600 and you can choose the lsa.
On sale also for $349. add pac1218s for $130 more.

 

True. Geoff does as well. Do not know if he is still a sponsor. I have been away from the site for a few months.

 

Lingenfelter GT2-3 is a good choice

Or message soeedtigger on here. He works for cam motion and can custom grind you anything

 

The later ls6 cam makes about 20-25 more rwhp peak to peak but 40+ more by 6500 rpm

 

I agree with other posters that the "mild" Cam Motion cams seem to have lift that is too low as LS1 engines love lift. There may be a reason for their choice there though. My Cam Motion 218/226 cam which is no longer sold has higher lift and is very mild compared to the majority of cams. I would actually recommend that for a car like yours but it would need some tune work to be really stealthy based on the work done on my car.

However based on my experience, I agree with the recomendation of tech@WS6store, this TSP 216/220 cam on 114 - 116 lsa should be an excellent choice. I would go 114 which is -10 overlap, same as my current cam but I've found that is not completely stealth in my car so you may need 116.

Knowing what I do now, to try and retain the previous power I had (I dropped nearly 25 hp going from a Comp 216/220 to the Cam Motion Cam) and the low down for my heavy car (not a consideration for your car or things like older Camaros and Corvettes) I would probably choose this TSP cam, though I don't know who actually manufactures it and if the lobes are quiet and smooth like Cam Motion.

 

Tsp makes their own cams.

Our high lift hot cam is also mild and makes good power. Sounds great too.

Thanks for that info, I wasn't aware that TSP actually manufactures their own cams, I knew they used to be Comp based. I wonder how their lobes compare. I've not seen their newer stuff used down here in Australia (seen heaps of their earlier Comp manufactured stuff though).

I have listened to your Hot Cam, just for anyone that is curious, while its always hard to tell in videos, just comparing it to my Cam Motion cam, mine seems much more mild. Different car to mine and different aim for the cams though I would imagine.

 

Does Kelford have a good reputation for LSx cams?

I did a quick read on that Cam Motion cam and it appears it is designed for GM LS2 springs or similar. I recall note even the old TR 220 cam with .550 could not use those springs as the lobe was very aggressive.
