Was going through my carb "collection" looking for a Q-jet to re-build and came across an NOS 4-jet that a guy gave me as partial exchange for machine work. Had almost forgotten about it. Has the heavy iron base plate. # 7023184 ... comes up as 1963 marine application. Which seems consistent with what the guy told me. Are these compatible with the older Pontiac AFB intakes? Anything particular to the marine application I should know about? Thanks.
