New ignition switch, all new wiring everywhere, new fuel lines/ sender, tank , and no cap on it right now so venting isn't a problem, new fuel pump, cam installed correctly (would not run smoothly ever if this was the case, but good suggestion Lee), swaping both carbs do the same thing.
With the now clear fuel filter on it I can verify it's getting fuel.
I'm going to try Ken's suggestion when I get back and take the car out of the equation. There's got to be a short somewhere that's doing this.
I also had this: just placing the key in the ignition switch, not turning it on... just slightly putting the key in....causes the horn relay to click and the ALT idiot light to go on showing me that yes, I'm an idiot!

This initially happened with the door open, and I'd push the door jamb switch in and it would turn the light out. Releasing it would cause the relay to click and the light to go on. I disconnected the door jamb switches and this stopped the light coming on and the click. Before that I disconnected the horns, alternator, ballast, coil...all one at a time you see if any was causing a short. Same results.
It's a stumper men......
