View Full Version : 4 bbl intake question

06-12-2006, 01:31 AM
Just a quick intake manifold question. I notice that some 4bbl intakes have four carb holes all separated. I just picked up a 63 4bbl AFB stude intake and there are small 1" deep slots that connect pairs of the carb holes. Why are the slots necessary? Is that unique to AFB carbs?
