Help me pick my Stealth Cam

After a lot of reading and comparing I located the cams above as some of the most stealthy sounding cams. Don't get me wrong: I love the lope of a cammed car but for this project it is very important that the car sounds as stock as possible. The most important points are:


- No lope. The car should not sound camed.
- Gains under the curve. To me the lower and mid powerband is most important.


Based on the specs above and your experience - which cam sounds the most stealthy? And which one shows the best gains in the lower and mid powerband?








P.S: I decided to ditch the following Cams. Although they are very nice cams with good reputation they have at least one criterion which doesn't fit my needs.

- LS9 Cam...........................(Although the idle is as stealthy as it can get - the gains are just to small)
- Lingenfelter GT11..............(First this was my favorite cam - but the lifts just seems to extreme)
- LG Motorsports G6XE.........(To less information - no soundclips available)
- JRE Smooth Idle Cam.........(Nice Cam and the support from Ted is outstanding. However after listening to some
............................................youtube clips I realised that there is still some lope)

Your going to tell it's not stock even with those cams but not very noticeable. Why no lope?

Not shure how much of the lope a tuner is able to eliminate.
Thatswhy I searched for cams with the least lope (LSA > 116)

Absolutely a good tuner can smooth it out very nicely. Check with Ted Jannetty and you maybe able to get a cam + tune to go with it.

which cam sounds the most stealthy?

Crane has a specific cam in what you are seeking.....also if you are looking for stealthy noise, an exhaust upgrade is your best bet!

Smirnoff thanks for the suggestions. Which crane cam do you mean? Can't find in their website.

Regarding the exhaust upgrade: I'm planning to either install a borla touring or a magnaflow street catback to keep things quiet.

Are you trying to build a sleeper? Lope is a good part of the fun with a cam!

i have heard the 1C in person. doesn't really lope but still sits at idle loud. probably with a quiet exhaust you would be good. i am guessing the other cams are similar to this one.

Mike - Have you heard the 1C in a G8 or a Camaro? I heard it in a G8 and it's definately one of the most stealthy sounding cams I ever heard.

But if you tune out as much lope as possible to change the sound of the cam - don't you work against its nature and sacrifice performance?

I have heard that CheaTR cam on a 4th gen LS1 and couldnt believe how stock sounding it was. It might of had stock manifolds though as I cant remember for certain. Cant comment on the others though. Have you considered the LS9 cam along with some 1.8 or 1.85 roller rockers? The gains might be as much as the others with that setup. Only drawback is that it would end up costing you more because of the rockers.

Vader - thanks for chiming in!

Good to hear some real life feedback about the CheaTR cam. Still wait for some answers from Thunder Racing ...
On the other hand Livernois is great when it comes to customer service and communication - they where a big help!

As for the LS9 with 1.8 rockers I'm quite not shure. It's definately an interesting alternative but if I got this right 1.8 rockers will increase the lifts. If this wouldn't matter I'd choose the GT11 as well into my top 4.

Also are there any downsides if the intake and exhaust lifts are identical?

The LS9 cam with 1.8 or 1.85 roller rockers still wont have near the lift of the Gt11. I think it will be around .600" with those rockers. As far as lift is concerned with the GT11 cam I think as long as you have a properly matched spring the lift wont be a problem. I have PRC EHT springs with mine which easily handles the lift. I was also pleasently surprised by the fact that the valvetrain noise is no louder and maybe even quieter than stock L99. I really dont think LPE would put this cam in so many warrantied packages if they thought it would be a problem for reliability. As far as I remember this is the same cam they put in installed engine packages with 3yr/36k mile warraties. How many high performance engine packages can you think of that have that kind of warranty?

True. I think I'll give that one a try.

The only thing I would like to know is if there are any downsides of identical intake and exhaust lifts ?
The Livernois 1C has: .600"/.600"

The tuner cannot take out as much lope as you think, unless you are willing to run it in open loop, and richen it up at idle. Fuel will really calm it down, if you throw some at it. Idling at 13.0-14.0 will cut the chop down quite a bit, but it wont totally solve/cure/eliminate the lope.

Louis - thanks for chiming in. Great post!

That's what I expected (Although quite a few dealers told me that most lope can be tuned out). So I guess the time spent was well worth to find some mild cams which come from factory with almost no lope.



Based on the youtube clips - the Livernois 1C is the most stealth sounding cam out of this four. Not shure if based on the specs the CheaTR should sound even more stealth.

Right now it seems like the 1C will win.

They may be talking about "surge" which is in gear, rolling at low RPM. "Lope" is idling, in neutral, think "brapity brapity brapity".....

Both can be minimized, but not entirely eliminated.

Yes I know. For this project "no lope" is the most important thing.

So which one would you choose?

You do the same thing by selecting a CAM based on how much lope it has as opposed to best power under the curve. Most people are dopes and if you putting an exhaust on it anyways then they wouldn't know whether the lope was a CAM or exhaust.

Just tell em you gutted the cats.

Unfortunately the experts at the road traffic licensing department over here arent "dopes". So trust me, the car shouldn't sound like it's cammed.
