Thanks for the input everyone! I'm certainly leaning towards the cam being the culprit. I've got a MSD 6AL ignition box (no rev limiter chip in it) with a MSD Pro Billet distributor. I have the fuel pressure regulator set at 6.5psi. It seems to bump up to 7.5 when I launch. The gauge is next to my right knee in the video. I used fresh 94 octane gas. The plug wires are old but I checked them out this spring and the all tested within spec.
I'm not trying to ring out every last tenth in the car. Probably won't be back at the track until next year. I won't change the cam. It drives around town well now and can do burnouts with a 21.5" wide tire. grin Couldn't do that before. Was a little disappointed because the car seemed faster. Hopefully someone else can benefit from this thread.
