I have included two exploded view illustrations of the Holley 6-pack 2-BBL carbs
(and a Picture of a Holley 950 cfm 3-BBL carb).
The first thing that you will notice is that the old 950 3 BBL carb used a Secondary Vacuum Pod with 4 screws sealing the lid on the pod.
The Holley 6-pack carbs used a 6 Bolt secondary Vacuum Pods with 6 screws sealing the lid on the pod. They are not inter-changable.
The second thing is the 6-pack carbs get their vacuum signal to open the pods from a source in the center carb (like the 3-bbl)
but then use two vacuum hoses to supply that signal to the end carb diaphragms. There is a external nipple on each carb close
to vacuum pod mounting screws. Signal goes from the center carb thru the hose to the pod.
More on 6 pack carbs tomorrow.
