WOW thats sweet ..........

What do the heads flow after you cnc them ? stock valves ?
Did you mill the heads ?
What is the specs on the stage 3 camshaft ?
How much more hp/tq do you think it would make with Carries (ETP) carbed cnc`d intake and a carb/dominator ?

Peak numbers were 386 on the intake and 234 on the exhaust. Low and md numbers picked up quite a bit. The factory head stalled at around .650 lift and we fixed that issue. I'm hoping to have graphs soon. EDIT JUST TO SPECIFY, these numbers were from a SuperFlow 1020 bench calibrated with plates borrowed from the OEM and a SuperFlow 600 would read roughly 10 CFM more.

We used stock valves and milled them slightly for trueness.

As far as cam specs, Dan did a lot of development on the dyno and tested a lot of cams and we typically always give the specs, but lately have been noticing a lot of people copying our grinds. He would like to keep these specs proprietary.

We didn't do testing with a carb manifold, but I would guess it would pick up quite a bit.

Thank you,

I was there for a few of the dynos. From what I could tell the idle sounded mean, but was very tame. The car wasn't surging and didn't stall once while I was there. With the way the exhaust was set up it sounded just as tame as stock with the cut outs closed. I'm sure Rick can give you some more detailed info. :thumbsup:

It idles great and in all honesty, it drives pretty good considering the size of the cam. I wouldn't recommend it to someone with a daily driver or that was worried with great drivability, but I'm pretty picky when it comes to drivability and I would definitely have no problem with it in my weekend toy.

Here is another video of it...

Couldn't of said it better myself. For a DD I don't know if I would want a cammed car after riding in a turbo/procharged car its kind of a no brainer on which route to go for a DD. Though your vette idled like a sissy. :lol:. I would hate to run into that z06 on the highway. :redface:

I guess what im saying is, does the cam make the car Shake on idle or low rpm cruising?
Click to expand...

Any cam is going to have a slight shake. Dan had the car at some low RPM's on the dyno and it didn't seem to buck at all. I would say that cam is going to shake a little bit at idle, it's pretty big. I'm sure Rick will elaborate, he spent some time in the car. Although it's not going to shake the whole car and boggle your eyes, but I imagine you can feel it. If you want the best drivability for a street car you drive a lot or a DD that is silky smooth, you would be better off with twins or a Procharger.

EDIT- Oh and Rick did DD his C5 Corvette which had a head/cam package. I'm sure he can tell you what cam size would be tolerable for daily driving. Its been a few years but when I went for a ride in it, his drove damn near like stock but the cam was a lot smaller than the one in this Z06.

UPDATE - Last night in Orlando, the car went 9.95 @ 139.18 MPH!!! :ohmy:

Trying to get a better slip... this is all I could get so far (hard to make out though)

As great as it was that it went that fast, I think it's more amazing that it has a stock rear end/axles and stock suspension and 60' like that!
