Just like the title says. Is anyone on here, from F-bodies, Corvettes to CTS-V's, running Brian Tooleys stage IV camshaft and matching springsin an LS6? (5.7 Engine)

The reason why Im asking is Im very heavily leaning towards his combination.
The Spec's for the cam is as follows 235/242 .621"/.592" 111+3

The reason why I'm asking is becuse I'm 99% certain this is the cam I'm going to go with, the only problem is I can't find anyone who has it.
I was courious how its street manners were, driving in 6th, low end torque?

How does it sound while idleing and so on. I know this cam can be greatly affected by its tune. If you don't get it right the idle will be all over the place but when you get it spot on its perfect from what Im told.

I was hoping someone on here would have vid of a dyno pull or even just a start up and idle vid. I was also curious how the cam effected your brakes since the cam tends to pull tad lower vacuum, nothing that a vac pump could fix.

I'm running the stock 04-05 LS6 Cam (Stock LS6) in there now. This post isn't about polishing the heads, That will be later when I upgrade to AFR's.

Anyone who has this cam/spring combination either post a vid, a very good description on how it runs or PM me

Thanks everyone,
Steve Thomas

I'm curious as well. Hopefully Brian will pop in here with some info & results. Good questions, OP.

With 16.5 degrees of overlap, it's going to sound very "healthy" to say the least. It's a fairly large cam, but the overlap will help with the low end torque and power under the curve.

Its very similar to a G5X3(234/242) or a Comp LSr 460 cam(235/243)...like said above, with the 111+3 LSA and 16+ degrees of overlap, its gonna have a very choppy and slobbery idle...should sound great and make good power...proven specs.

I've had a couple of long conversations with Brian, on the phone as well as back and forth emails. He unfortunately doesn't have a vid to reference. After I do the cam install late this summer I will be sure to update the thread with it.

That's a *lot* of cam, especially for a street car. It's going to be tough to tune for a clean idle. Bottom end is going to be lazy, and it'll probably surge at low rpms.

Any competant tuner will be able to make the car drive great with little to no surge at low RPM's. Even though this cam is rather large, it's not going to be as lazy as you think in the lower RPM's. As I said above, it's on a 111+3 LSA and has 16.5 degrees of overlap, so that's going to make for more torque and under the curve power.

Here's the dyno graph of a C5 Z06 with stock heads and intake. It made 450ish on a Mustang dyno, and still made 440 rwtq.

I had another guy with a C5 Z06, stock heads and intake, switched from a 224/224 cam to my Stg IV and picked up 40 rwhp, but amazingly picked up 30 rwtq. He went from 410 rwtq with the 224/224 cam to 440 rwtq with my Stg IV.

Here is what the tuner Daniel Goodrich said: The end result made great power, sounded great and drove smooth as butter. We were all pretty amazed with them. I wish you could have drove the c5z I tuned for Jared with that cam, I feel like you would have really been amazed with how smooth it was even at say 1200rpms in 6th..

Brian, please shoot me a ballpark... With my mods, and the AFR heads, where do you *think* I'd be?

I'm not afraid to flycut. At all.

Run 5 we lost signal there for a sec




Run 6 the stock clutch let go and we shut the run down early.

What are your current cam specs?

Rise of the Phoenix

iTrader: (27)

His current cam specs are 229/236 .631 intake, .631 exhaust 112 LSA and 110 ICL. I know this because I had the same Ed Curtis cam that he does. Hope you don't mind me answering for you Dr.

dr_whigham

Not at all brother. And yes, he's right. It's on a 112+2, 110 ICL

I can't wait to install this recommendation. I have also had several email with brain ( I won't have cash for every thing until fall). I don't care what the hell it sounds like though. Only how it goes.
Good luck installing this, I doubt after driving you wil be disappointed.

I was just thinking... that the AFR 205 heads probably wouldn't like the exhaust duration on this cam. This cam is setup for a stock exhaust ports with 1.55" exhaust valves. I think it might still be fine for 1.575" exhaust valves, but I'm a little unsure of how it would react with the 1.600" exhaust valves in the AFR 205 heads.

I know we've seen the AFR 205 heads be sensitive to exhaust in some testing that I was involved with in the past. When I measured the exhaust port volume a long time ago, it seemed like it was around 88c, which is really large compared to the intake port volume.

I've heard the same, that the AFR's can actually "over-scavenge" on the exhaust side.

Either way, EXCELLENT #'s coming from this cam!

Steve83ta

Im pretty much the same way. As long as it doesn't surge, and from all the research I've done I'm told it wont. I would love to do the swap this week, but I won't have all the cash together for another couple of weeks. From the cost of the package plus tuning its going to come close to a grand for the upgrade.

Steve83ta

Brian thanks for bringing that to my attention. Next year I was planning to upgrade to those heads. But now after hearing that Ill just stick with my LS6 (243) heads and your camshaft kit. I can't wait to start the cam project. I have 2 others I have to finish first before I can get to my own car.

Brian, how would this work with TEA Stage 2s? I still need to measure to see if the EPS 230/234 114+2 I have will fit. If I need to flycut, I'm going to say F it and go with this cam and mill down to 60cc.

Brian Tooley Racing

It might lose too much low end torque with 235 degrees of intake duration and a intake port volume of 225cc. My Stg IV cam still closes the intake valve 1.5 degrees sooner than your EPS cam, so it could make more power everywhere. Overlap makes torque, provided we don't have so much that we lose top end horsepower. The TEA LS6 Stg 1.5 heads that made over 500 rwhp had a cam very similar to this one.

4000 stall makes low-end less of a concern. Low overlap is why I went with a 230/234 114 to begin with, but I will probably want more power from this and a cam swap is the easiest and cheapest thing to do.
