I don't think so. 427 vette engine came with 3 Holley carbs with 2 vacuum secondaries. It sound to me more the center carb is leaning out. He may have to reduce the exhaust crossover from heating the center carb. It can also may have an internal vacuum leak inside the carb. Could be a warp throttle plate, too.
