Stealth II cam?
...........
I would go with Predator's design or even his design on a 114 lobe. It will not require a very high idle to completely hide the lope.
The CheaTR is a nice cam, but optimized for stock manifolds. It will work, but again in this situation, reducing the LSA would make more power and accomplish the goal.

Peak lift is just one point on a continous distribution. The high lift cams typically have more duration at .200 and .400 lift so the area under the curve is greater than the same duration (.05 measured) cams with lower lifts. This is where the gains often come from.

The other reason is the lobe rate at various lifts, .006/.050/.200/.400
That is why I do not agree with Zach's statement. And i've tested that various times in my cams
If you are going for a sleeper you should keep your manifolds and just get the cheatr cam or something close to that...with headers the cam lobe is magnified dramatically, much harder to hide...stock manifolds flow alot better than most people realize...with the stock cam and 3360 race weight and stock manifold and cats on the car i went a best of 11.72 at 115.4mph the da was -950 ft but on a 0 da da the car would run 11.90 all day...this was on stock manifolds and cats...just think if i had the cheatr cam...
if i were to go the sleeper route it would be ported and milled 241 heads with a cheatr cam or something close with stock manifolds...maybe even add a hidden 100 shot dry kit...you could run mid to high 10s with that setup...
and everyone would think you are just another stock head, stock cam, mild bolt-on car who doesn't even have headers yet...
fyi my qtp headers and ory added me around 12-15hp

Well Im pretty much sold on getting the Stealth2. I thought the stealth2 with LT's would still idle like a stock motor with LT's as were theh cheatr cam would have alittle lope with headers. Im not looking for blistering track times, I just want a nice street car that drives and sounds like stock with bolt-ons but with more power.
Im looking for a cam for a stock 5.3 in my 03 Silverado, it will have LT's and a cat back, cold air intake and a wheatly or nelson tune, how well do you think the stealth cam would work for this combo?

The CheaTR is -13* overlap so technicaly quieter than the Stealth 2

On what information, or lack thereof, did you reach that conclusion?BTW, As someone else pointed out, if you want true stealth, skip the headers and go with a cam designed for stock manifolds. Most Headers are thinner and louder than manifolds.
I was told this info when I called MTI, Im putting headers on regardless, so I based my desicion around this. I was told that the cheatr would have more of a noticable lope with headers than the stealth2 would. Since I'm putting headers on, wouldnt it seem like I would be better off with the stealth2 since the cheatr was designed to work with manifolds? I do have a really good tuner to tune my car so even then I would amagine the idle could be played with until it sounded stockish?

like already stated i have a stock cam and with headers and still stock exhaust with a cutout and people think i have a cam because it screams...
if you want a true sleeper go with the cheatr and stock manifolds...i dont know why you are so fixed on the headers it is really a waste of money if you are not looking to put a big cam in and you are trying for a sleeper and dont care about huge times...
u would be better off spending the money on ls6 intake...
curious to why you want headers so bad...if you want a stock sounding cam...
listen to predator he knows what he is talking about...

Things seem to be getting alittle out of context here. I understand that it wont be 100% stock sounding with headers but I got an awsome deal on a set of use LT's from a friend, also I will be running a catted y. People seem to be getting off track here. Earlier in the thread I said which cam would make more power with headers and I said I want a car that sound like stock motor with bolt-ons, headers being one of them. If it has a tiny chop to it, I'll live with it, I just didnt want the crazy lope like most guys have. Im not new to cams, My LT1 has a 24x/24x on a 106LSA, and trust me that lopes extreamly hard and sounds like a 9 sec monster but it aint that fast. I dont want my SS to sound faster than it really is.
Heres a sound clip of the stealth series cam I pulled off of MTI's web site.

That second video sounds almost exactly like the set up in my sig below. I'm currently running mids with a Borla cat-back but will be switching to LT QTPs this winter when I install my ported 5.3 heads.
Don't worry about others telling you to run manifolds. I dosn't matter if your car is quiet with manifolds or louder with LTs. People are STILL going to under estimate what the car is capable of. I routinely whip up on Vettes all the time, most of them never saw it comming until it was too late. Most swear the cam is stock.

I put down 399whp with patriot stage 2's/TR CheaTR...through a Th-400...good power is achieviable with either. The idle is subtle and not THAT notiable with my cutout closed.
I called both TR and MTI about the CheaTR and the Stealth2. I've narrowed down my search to these 2 cams. Now my problem is which one? They both claim about 40rwhp gain with supporting mods which I will have. Maybe I'll just flip a coin, what you guys think?
You would barely be able to tell the difference between the two cams. The cam with the higher lobe separation would peak slightly later maybe 200 rpms thats all.

A tad more overlap, a tad more DCR, a touch of more exhaust, all together a tiny bit more ponies under the curve.
