Well, it's my turn to ask for suggestions..

Ok, i'll try to answer some of the newest questions. 1st, yes, the throttle goes wide open. Just so you understand, even if it was only coming open 1/4 of the way, it should have a lot more than what's here. 2nd, car has the same power in all three gears and in reverse. 3rd, I have not put a vacuum gauge on it because I don't have one. 4th, I got rid of the single exhaust and put a temporarily dual exhaust with glass packs that end before the rear axle when I installed the motor. It has manifolds, no headers. I have discovered that if you floor it, as the rpm's build it starts to cut out. I don't know if this would be a new clue, but i'm truly believing it's the cam.
