C6 Corvette ZR1 & Z06General info about GM’s Corvette Supercar, LS9 Corvette Technical Info, Performance Upgrades, Suspension Setup for Street or Track
Looking for opinions on this cam specs, relative to what I am looking for.
The car is an 08 Z06 with PRC 265 heads and the following “Black Mamba” cam (See below). Apparently these cams are custom cut for each individual customers needs, so not every “black mamba” is the same.
Anyhow, These are the things I am looking for in a cam.
-Don’t want it to be really hard on the valvetrain. I don’t want problems, I want to drive with confidence.
-Prefer it to not have a lot of valvetrain noise, but not a huge priority.
-Not a total PITA to try and drive smoothly in stop and go traffic. (For the record the car as the stock clutch).
-Would like a respectable amount of torque down low. Don’t want all the power to be up top, where everything other than winding it out is lazy so to speak. This is not a track car, just a street car.
I don’t have the car yet. It will arrive in approximately 7-10 days, so I have to get the car and drive it around to see what I think, but I have a feeling I might want to swap it out for something like a torque 110, for easier drivability and peace of mind. And speaking of that, are there any “latest and greatest” cams that are better that have surpassed to the Torquer for a DD type cam??
That is pretty much a monster cam and would not be a fun DD. Once you get into the .640ish range with the stock rockers you are approaching a lot of valve train stress with side loading on the guides. .648 is not over the top but it's getting close.
I would talk with Patrick G in Victoria TX. He is an expert on specing cams.

I looked and even the torque 110 has a lift of .648

Hmmmm!! I have the Texas Speed LS7S cam. I just drove it 2hrs to an event here in Florida and it drove great. It's subjective, you ask 10 different people and you will get 10 different opinions. My advise, don't get anything smaller than what's on that cam sheet. You wont be disappointed.
I suggest you drive the car around for a while. Figure out what bothers you, then post back.
How it drives is only one part of the equation though. But speaking of that, can anyone comment on how the torque should be with this cam? Will it be pretty doggish down low? WHat about the mid-range?
The biggest thing for me is how hard the cam will be on the valvetrain. With the PRC 265 heads and their springs (Assuming .660) should I be ok, and then just change the springs out every 30k miles or so? I don't really want a risky setup where I'm taking my chances, so to speak. These LS7's are too expensive to have a risky valvetrain, IMO.

No it will not be doggish down low, as has been suggested drive the car first before you switch out the cam. That cam should pull from 2,000 - 6,000 rpm and carry the power to 7,000. Myself I'd plan on changing the springs out at 20k miles but that is my preference.
It was tuned by Wong Performance in WA. From my understanding he is a good tuner.
One other thing is I just checked and the PRC heads come with a choice of either SS, hollow stem, or titanium intake valves. They say they recommend no more than .616 lift with the SS valves!? The cam is .648 lift, so I will have to verify what's in there.

Thoughts, suggestions?
Custom grind endurance lobe cam from EPS or CamMotion.

Called TSP and found out it has titanium intake valves.
Sigh of relief!
I assumed it would be, but it's always nice to be sure!
Interesting. There is a lot to read there and on Camaro5. If you know the whole story is it possible to give us the cliff notes? Did Tom ever defend himself or offer an explanation?
From everything I've read, little to no difference from an off the shelf grind.
True....I had CamMotion custom grind me a cam for my H/C/I Z upgrades I did in the spring....they had it to me in less than a week. $475 out the door, custom made. I wanted something very driveable.
