Spec me a sleeper cam!
Spec me a sleeper cam! Hey guys I am looking for a sleeper cam to go in a 02 Z28 w/LS2 conversion. The car has Pacesetter 1 3/4 LT headers, off road Y, and stock catback for exhaust mods. I want it to be a true sleeper cam with no indication of lope @ 650ish rpm idle. The car is an auto running on the stock stall for now. Probably end up going with a 3k stall in the near future. Most likely I will get an electric cut out as well to bypass the stock muffler at the track.
What are your recommendations?
What are your recommendations?
Use Comp XE lobes and 918 springs to keep the valve clatter down. (more stealthy)
216/220 .561/.564 115LSA +3 advance
If this were a 6 speed, I'd recommend +1 advance, but for an automatic, you want +3 advance to have all of your power in by 6000-6100 rpm (to preserve tranny life and give more grunt down low with stock stall).

With an automatic, probably around 35 rhwp.

CheaTR is not as stealthy as the cam I recommended. The CheaTR will have a noticable beat to it at 650 rpm. Great cam, but only stealth with a higher idle speed than 650 rpm. There is no need for a 230 duration exhaust lobe when you have long tube headers. The CheaTR excels with stock exhaust manifolds.

I thought the CheaTR camshaft had a higher peak RPM (6800 or so) and I wasn't looking to spin the motor that high. Not yet at least! I also came across the Lingenfelter GT11 cam 215/231 .631"/.641" 118 LSA, but I figure thats very similar to the CheaTR. Maybe has a few extra hp up top. I'm not against running higher lift since after about a year or so I plan on doing an L92 top end conversion on the car. Patrick what kind of gains would the aggresive lobes and higher lift gain? I would suffer some valvetrain noise for a few hp/trq.

Also, the LS6 lifters in the CTS-Vs are not any quieter than other factory LS1 lifters.

There is no need for a 230 duration exhaust lobe when you have long tube headers. The CheaTR excels with stock exhaust manifolds.
Patrick, can you spec something that will work with the stock exhaust manifolds/cats and nitrous that will be a good sleeper cam with near stock drivability on a M6 99 Vette, using the 918 springs for less valve train noise.
I was looking into the cheatR and if the idle lope at ~650rpm is the only draw back i may be able to work around that , it sounds like exactly what i was looking for. I may add long tubes and a later date but Im kind of a noise/resonance **** !
I ran an LPE GT2-3 207/220 .571/.578 118 on my 02 Firehawk. It sounded completely stock. With ARE heads (and they sucked if you guys recall), I made 385 to the wheels - about +60 RWHP from stock. That was on the stock tune, too, I didn't even re-tune it other than turning of Cat Overtemp and some codes. You couldn't tell it wasn't stock, though, that was the great part.

Most folks only know I have the cheater in my car when I tell them. Unless you really know what you are listening for then you can tell but I would guess about 95% people out there would not know it by the sound. However like Patrick G said it is good for use with a mostly stock exhaust setup such as the manifolds. I just havent changed it because I dont wanna lose any torque going to a bigger cam. Good luck with the cam search. I dont know why you would set your idle at 650 though I thought it is 800rpm stock settings.

He has an automatic. 800 rpm on stock stall starts to fight you a bit at a stop. You can live with it, but 650 will be nicer for a daily driver.
whats the best sleeper cam for a stock 01 motor with ls6 intake and 1 3/4 to 1 7/8 stepped longtubes to bassani true dual through x pipe, looking for as close to stock idle as possible but also a cam that can benefit from exhaust mods and other bolt ons without being too noticeable as it is a dd

I thought that Predator Z was running well into the 11's with only a Stealth II (forget mfg, low duration 'sleeper' cam) and headers on an A4. That is pretty quick for a "Sleeper" cam...
