I'm looking for additional recommendations for a stealth cam for my 2016 Chevrolet SS. I don't want anything that really compromises road manners or reliability for power, I'm just looking for whatever bump in power I can get without ruining the cars drivability. Currently the car has ARH long tubes, high flow cats, x-pipe etc to stock mufflers, intake and tune. The car trapped 114 mph with these mods last time out. I'm looking for a mild cam that will get the car to trap 117 mph or so. Two cams I've been looking at are the Livernois 1C cam that they designed for the G8 GXP, and my tuner recommended the Lingenfelter GT2-3 cam, which seems like it was mainly used on smaller displacement LS engines, but he says he likes that cam as a mild "stealth" cam very much, and it's lift being less than .600 makes it somewhat easy on the valvetrain, which is something else I would like.

What other recommendations would you guys have?

Check with Cam Motion, Texas Speed and Performance, Brian Tooley, Tick Performance, for starters. There are others. Look into truck cams , as they have the performance characteristics you are looking for.

We can custom grind you the perfect cam for what you want!

Thanks for the recommendations. Just e-mailed Cam Motion, that's who Nick at ARH recommended for me to contact.

One (or two) I noticed on Cam Motions website that caught interest are these two:

"Titan 1"

And "Torque Titan"

How would these 2 compare to each other and the other cams I mentioned? These seem nestled nicely in between the Livernois 1C and the Lingenfelter GT2-3

We have 2 torquer cams that make good power too. one is a 217/226 .610/.612 115+2 and the other is a 221/229 .612/.620 116+2
They both sound good and make alot of low end power and mid range and dont need any stall converter. The cams themselves are $385 and we either use the Pac1219x or a btr dual spring. Price varies there.

Blackdevil77

Thanks for the recommendations. Any options similar that keep the lift to .600 or less?

I can't find any videos of the Cam Motion cams I listed in any cars. Anybody use either of them and if so, any videos?

I previously used an EPS 218/226 .595"/.598" @117 that idled smooth in my LS1 and pulled strong to 67-6800 with dual springs and hollow valves
That GT2-3 has a great split that works well with the rectangle ports or EPS also sells a 214/232 that might be the perfect "in the middle" for you

Why less than .600? we have some on a .585 .598 also though

G Atsma

Are there valve springs that will live longer than 50,000 miles at .600 or slightly above?

tech@WS6store

iTrader: (2)

Yes. We carry at least 7 or 8 that will. They arent expensive either. Going above .600 lift doesnt mean some crazy aggressive lobe. Nor does it mean accelerated guide wear. Quite a few of the BTR cams have over .600 on the intake and some both intake and exhaust.

G Atsma

OK, thank you! Puts to rest some "sage truths" floating around the LS world...

Blackdevil77

That was the reason right there. Less strain on the valve train for a car that's gonna be driven on road trips/vacations etc.

That's truly a myth. Esp with new lobe design. .600 isnt the magic number where bad things happen. Its only .600+ because of a 1.7 rocker. If you want to see how aggressive a lobe is now you nearly need a CAD map of both the opening amd closing side as alot are asymmetric now and can have a soft open and harsh closing or vice versa.
I did see an actual test of valve spring pressure on a high mileage spring set off some xer lobes. Since they are "so aggressive" youd expect at least 20 to 30 lb loss. It did NOT go as expected. Ill find it in a few and link you. Those lobes arent over .600 for most the durations til mid 230s even.

Some or perhaps most of the "myths" surrounding the magic .600" lift is due to the fact that the factory rocker arm tip runs out of travel. It then binds and scrubs the valve tip.
LS3 intake rockers seem to magnify this due to the offset.
When the cam lobe (no matter the aggression) and the lifter continue to force the rocker tip beyond its geometric shape, the valve guides will wear out faster
IMO having non or slightly milled heads, thicker factory gaskets, and GM lifters that like a bunch of preload all help the factory rocker start lower(position) on the push rod side which maximizes the tip travel(pad) to effectively have success with a .600"-.610" theoretical lift
After all the deflections, the "net" valve movement ends up around.580"-.590-ish range

G Atsma

Maybe someone should make stock-type rockers that have a more rounded tip that won't scrub or bind on the valve tip. Or can the stockers be modified to do this?
Also, when is TSP supposed to come out with their roller-tip stock-type rockers(as I've heard them described)?

CAMMOTION PERF

The Torque Titan is an excellent choice. It was designed for exactly what you want. It will give more power everywhere without sacrificing drivability. It is a true no-sacrifice camshaft.

Blackdevil77

Awesome, that's what I was hoping to hear! How would you compare it to the Titan 1? I'm guessing the Titan 1 has a bit more of an idle chop, but would it make more power?

This is just out of curiosity, I'm strongly leaning towards the Torque Titan.

CAMMOTION PERF

The Titan 1 will definitely have a more noticeable idle. If using a stock torque converter, I highly recommend the Torque Titan.

It can and does sideload the valve yes. It can cause accelerated wear but normally the pm guides are very durable. As are new seals.
Ive hardly ever seen anyone check the wipe pattern on the valves when they install any cam. I am guilty of that on most builds as well. Shimming the rockers can help. When most cams are specd for a 7.400 pr, it is normally just a tad short to be on the upper portion of the preload window. That helps alot of issues. There are many ways to combat it of course But like i said its only .600 because of a 1.7 rocker. Had they used a 1.8 rocker, even less lobe lift would be .600. Most 1.8 rockers though are a roller tip. While sideloading and scrub are bad things, guide wear happens with any lift. I've personally seen some 4.8s and 5.3s that have such bad oil issues and its because the guides were so worn. This is on all stock trucks. I cannot really explain that one.
I do hear what you are saying though and do agree, but so many cams now are using over .600. I haven't checked any of the high mileage setups either. While they dont seem to have issues, you just cannot tell without taking some mics to them. I have not seen any long term tear down threads on the issue either. Some of it can be attributed to oil quality as well and use of the vehicle/engine.
