My 327 was doing that and it had the wrong spark plugs in it. They were too short it was driving nuts!!! Put a longer plug in runs fine!

One of the vacuum ports on the carb. not plugged or the carb gasket? It will do that if the brake booster line is disconnected or leaking. Didn't hook up the correct vacuum lines to carb ports?
