I'm still trying to figure out my new camera. Just need a little more practice. The sound clip really doesnt do it justice. I'm going to do some more till i get a good one.

Before the cam, stock stall with 2.0 60's. With this cam and no stall my 60's suck, but i still think i can do a little better.

Lots and lots of weight reduction helps. lol

I'm hoping to get it back to the track soon for some new times.

Sounds real angry, I like it...

How was tuning the cam? Any surging, stalling, or driveability problems?

Well, it was tuned with edit awhile back, and i also have a HPP3 and Jet stage 2 chip. It was originaly tuned with edit for the heads and bolt ons, and the rev limmiter was set at 6800 rpms. I kept the HPP3 to change the shift points at the track but that was it.

Since the cam install I've added the 93 tune to up the timing some and the Jet stage 2 chip adds 10* of timing at 1500 rpms. So with all the added timing its running real strong now. No audible detination.

As far as drivibility issues it runs and drives awsome. Even seems to get the same gas milage. Only issue right now is the lack of vacume at stop lights. It idles down to 300-400rpms and is only pulling 1-3inches of vacume.
A good 3500 stall should fix that problem though.
