I think the biggest thing we forgot to ask was is your car a MN6 or MXO6 (A6)? The cam selection will be different with the trans. I stayed on the mild side due to my auto trans and not having any plans on putting in a stall convertor.

 

Mn6

 

I couldn't have said it better myself!

We're starting to put CAM's car backtogether this week.....

Now... "THAT'S A CAM!"

Chuck CAM (I mean CoW)

 

Cam tolerance depends on the individual. Mine is a 224/228 XER grind on a 114, with CNC ported 243 heads and tuned by one of the best in the business. Car puts down 485/442 on 91 pump gas, and Charlie spent a lot of time tuning it for best behavior on the street. It behaves near stock in 90% of part-throttle situations. I have done 2 1000+ mile road trips and I trust the car and it has run just fine. That said, you always know it is there, it misbehaves from time to time, and I would not want any more cam than that.

Plus, I believe this cam is just about perfect for the 6.0L. Less and you leave power on the table. More and drivability deteriorates real quick in exchange for single-digit gains in peak power which occur in a narrower and narrower band. It is an increase in power that only the dyno will notice. In my opinion, a 224/228 cam is a great choice, and you will not be able to exploit the additional power of a 232+, G5X-whatever, MS3 or similar on the street.

I'm sure some will disagree. Bear in mind that some drive their cammed cars very little on the street and do not rely on them for commuting. I am curious how many with bigger cams (228+) have taken their car on a cross-country trip. To me, that is a key delineator.

Also bear in mind that speed shops have typically lost some perspective on what a "little" cam and what "adequate" power is. When you spend all day tooling around in 700HP cars with 427+ CI, nitrous, 244+ cams, blowers, and turbos, your perspective may be a little different from the typical street driver. I am not saying they always recommend a ridiculous cam. I am saying that their tolerance for the downsides of bigger cams may be higher than yours. The best really is to ride in or drive a cammed car and see if it suits you. You'll know pretty quick.

 

a 228/232 - 114 LSA w/ .598/.601 makes for a very driveable, reliable, & hi performance LS2. I think this is an excellent choice for a cam only swap, of course that means no heads, not bolt-ons. I have an '05 6MN making 452rwhp/418rwtq with the following mods:

Vararam & spacer
Ported FAST intake
1-3/4 Kooks, 3" X & mids, NPPs
U/D pulley
160* stat
Tune by Carolina Auto Masters

The car has excellent street manners & w/ the NPPs closed you'd be hard pressed to tell the difference from stock unless you put it side by side with a bone stock car. Headers, FAST, & cam impossible to hide but it's very mild. I made 400 & 500 mile round trip road trips w/o any concern what-so-ever, & would drive it anywhere w/o hesistation. I just don't make road trips past 5 hours as anything longer I'm flying.

 

This set up sounds optimal if you plan to add heads a 224/228 making 485hp is very impressive & I can only imagine how very subtle this is to drive until you open it up. Nicely done!

 

Well said, TTRotary. I concur with your explanation of the 224/228 LSA 114 because I have that particular cam. But, with the L92/L76 stock heads combo. I made 440/407. After driving for several months, this cam is borderline as far as daily driving behavior....I wouldn't go any bigger than this for DD. It's just a fun cam to me....a mild shake and a little lope. And, my car turns on big time at high rpm.

 

Yes, especially since I am running stock mufflers. Stock quiet when it needs to be, and a real screamer when I want that.

I do not wish to give the wrong impression: we used every trick in the book to get to the 485, including unbelievably good head porting, .040 Cometics, vlve change, patriot dual gold springs, hand-ported FAST90 / ported TB, port-matching, UD pulley, race-ported oil pump, and of course intake and LT headers.

Then there are the 4.10 gears, 335 race rubber, CCW rims etc etc. Lot of work, but also a lot of fun and a total sleeper.

 

Crane is getting on the 224/228 bandwagon, with the LSHS series of lobes they have for LS High Speed applications. Look at the new 1449101 cam in this partial listing from THE CRANE WEBSITE.

I am putting this cam in my C6 in a couple of months, along with Livernois Stage 3 heads at 11.7 to 1 static, 8.7 to 1 dynamic compression ratios. Should be fun.

 

234/240, .598/.608 112+3 in my LS2.

Cam, Vararam, 1 7/8" LT's, Clutch/Fly were all installed in Florida in April. That week, I took the car with 400lbs of gear in it from Florida to Southern California, spent a week driving through CA, then up to Oregon, eventually on to Seattle to ship it here to England. It performed flawlessly the entire drive, save for a stupid Service Charging System message every now and then at idle due to the UD pully.

After awhile, my driving habits changed subconciously. I've noticed it now, as the car never seems to buck or surge when I'm driving, except when applying light throttle down a hill between 1400 and 1600 rpm, and I dont find myself in that part of the power band other than to accelerate through it, usually. Rarely ever on flat ground at anything above 1100rpm to I get any surging. And typically, it's exacerbated by the twin disc while cruising around in town.

Basically, I'm completely fine with a 240 .600+ cam for daily driving. I dont find it to be a burden at all, and I've only killed the car maybe twice in a parking lot after a hot start, trying to idle out of a spot with the wheel all the way to lock, slipping the clutch.

I've had cammed Mustangs, Subarus, and other built cars. This is by far the most civil, and happens to have the most aggressive cam profile.

 

I have the same experience as you with a very similar large cam. The ls2 computer is a wonderful thing. I daily drive mine in mostly city driving stop and go and it's just perfect. No problems, and I let non-car people drive my car and they have no trouble.

Turn of code P0621 (change it to "no error reported") with HP Tuners to stop that annoying dinging from the service charging system. Did it months ago and I don't have any charging system problems.

 

ok... how about a cam recommendation?

engine is stock other than Lingenfelter 243 heads, headers, Corsa exhaust, Hurricane CAI, computer tune, M6

 

Cartek 3X Cam is what i have. I would highly recommend this cam!

23x/ 23x, .59x /.60x with a 116lsa is what i have and the car just hauls and has GREAT street manners. The car has never stalled,stubbled what so ever.

Give Cartek a call!

Joe, thanks for the tip. I'll have to plug the HP in this weekend and take a look. And yourself and TonyB4 are two of the posters here I've become familiar with, simply because the two of you have a similar, although slightly advanced setup, in comparison to mine. Both of you guys have run some respectable times, and having that info sort of clues me in to where I could/should be with mine, one mod at a time - as I'm following the same path, coincidentally. The fact that both are LMB LS2's just like mine is probably conducive to that thought as well.

 

That Cartek cam that TonyB4 mentioned just above would get a vote from me for a viable option as well. I like the specs he's listed, and Cartek routinely pushes out some respectable cars. I've never dealt with them, but I hear the names of the wrenches at that shop tossed around quite a bit on the forum as top notch guys. I actually think that a cam like that, which is on the larger side, would compliment your ported heads well. Given a manual, I'd expect you'd see at least a solid 440rwhp, if not more with a nice tune.

 

I would think at least 440rwhp with a manual with the same bolt ons as i have.

 

Same performance from my cam. I have yet to drive for an extremely long distance but being my car is absolutely bearable in stop and go, shouldn't be an issue driving long distances. Most I've driven is about 75 miles one way on the freeway, no issues at all. The service charging system that comes on once in a while is annoying though. My car always starts (cold or hot), doesn't surge, die at idle, etc. My cam is a Comp Cams 230/236 .608/.613 113lsa on XFI lobes.

 

Bunk, don't try to fight it like I did for way too long. Turn off p0621 and make your life better.

Slickshoes, of course Blue cars are the fastest! Just look at the 1/4 mile fast list! An abnormal number of blue cars at the top.

 

 

Got a vid clip ? btw, the difference between your engine and mine would be my heads. So maybe close to about 480rwhp w/that cam on my setup?
