. Can't argue with the results though. I think he would think this is a great blower cam.

Blower cams....
Hey guys, looking for some advice on cams. I have an 08 ZO6 with WCCH ported heads, Vengeance Annihilator cam, Kooks headers, Halltech cold air, FAST intake and nick williams throttle body. I am considering doing a supercharger setup later on and was wondering if I would HAVE TO change my N.A. cam for blower cam? I know there would probably be a HP increase, but would it be a have to case? The cam specs for what I have now are .623 lift across, with duration at .050 int.239, exh.251 and a lobe separation 115. Specs are on 1.7 rocker, but i am running 1.8 ZO6 rockers. Any insight would be appreciated.

I think you will be fine with that cam and make good power, I am going to run a D1SC with a black mamba cam, not the most "blower" friendly so I'll pulley it for about 12 psi and with the boost loss hope to make 9-10 psi. So it should make good power up top

Thanks guys! This is what we were thinking. I just wanted some outside opinions. I just put this cam in and I really like it. I figured it would not be optimal with overlap, but wasn't sure if it could possibly cause a problem. I am not wanting alot of boost. The car still has stock ZO6 bottom end. Just looking to make around 6 to 8lbs. Maybe A&A v3 t-trim kit. Will be a few months away before doing. I still have not dynoed car with N.A. setup yet. Hope to be between 570 and 600 with current setup (at rear wheel).

Nothing worng with that cam, but a bit big for that small of a blower.
If it was my car-I would put the stock cam back in.
Look at how Rodney's car from RPM works with the stock C6 Z06 cam, 9.3@145+ mph.
The reality here is your limited by the stock bottom end and your fuel system-so say 650 rhwp-put the stock cam and let the blower do the work-after all that's why your buying one.
Now if you wanted to make 1K plus rwhp-that cam is a bit small-you need more exhaust duration-which means more overlap.

I've got a good cam that has a great idle. I just set it up a little bit different then most guys do on their blower cams. Has a baby idle(unlike my old C5Z06) but will kick the snot out of the ZR1 cam(which I had in my old C6 setup) anywhere and everywhere in the powerband. You won't see too many people running a similar blower cam in here. I absolutely love it, it is a comp grind and not a tuner cam.

I don't care if it has a nice lope, etc but don't want to deal with tons of surging. I had a N/A cam with 25 degrees of overlap and it drove ok but not great. My last cam was a 228/234 115LSA and I think it was a bit small. Idled fine at 725 and drove great. Leaning towards something in the ~230/244 116LSA range.

The cam I would suggest is much smaller than that-It will have a slight lope but will have no driveability issues, no bucking, no surging. It will make power right off idle to 7k.
I can pm you the specs but cannot post it. It's similar to our Stage 1 but slightly different. I'm assuming your using 1.8 rockers as well?

With your added displacement you can tolerate more cam, but its not necessary for your goals. Some guys like the choppy idle...sounds mean!
Anyhow, I like the cam you suggested it will drive great. Its recommended to choose softer lobes for FI, so keep that in mind.

Yah, being easy on the valve train is one of my priorties.
These two cams seem to fit the bill. Livernois is checking on custom grinding a bit more custom. Also waiting on IPS and some other shops to get back to me with custom cam ideas.

That is the key for a FI cam, we don't use any of comp cams using XER or LSL lobes.
If comp doesn't have the lobe we'll use Bullet-the lobe is the most important thing in getting a HR to make power-and with the blower that means RPM.
As far as overlap-my own personal cam has 24 degrees of overlap and can get driven anywhere-even my wife can drive it.
Now I won't recomend my cam to everyone-but if you want to make big power-don't be scared of overlap.
