It was the carb float bowl/accelerator pump well starving for gas. Rochester has baffles. I got new Quadrajet and it stopped. I seem to remember that a product improvement was made on the Q-Jet. Maybe you are missing the baffle. (You probably don't have a Q-jet).
Could just be float level/float drop setting......or a vacuum leak.
