Suppose we go from a 350sbc with a single 2 barrell rochester, properly jetted, and replace it with a 3 - 2 barrell setup. The engine size remains the same, the HP remains the same.
What would the jetting change if any?
Ie: would the jets be 1/3 as great as the single carb? Would they be slightly smaller, how about staying the same size or would they actually be larger?
Discuss your answer.
(the same would be true if we went from single 4bbl to tunnelram with 2 -4bbl or splits)

It would depend on the fuel curve of the carbs, but probably only slightly less.
