Carburetor Noise

Fixed an old 307 sb chevy quite a while back that did the same thing. Sounded like a machine gun outta the carb when the throttle was opened. AsRusty & yellow rose said Iit had a wiped out exhaust cam lobe. $20 says you have the same issue man. New cam & lifters and that 307 ran great! For a sb chevy that is!
