This discussion reminds me of the Dodge-Plymouth SonoRamic intake setup used in the early 60's on big-block V-8 cars. IIRC, the California Highway Patrol had some of these. The intake runners in racing models were 15" long, in others (CHP) were 30" long, a 4-BBL carb on one side of the engine bay feeding the bank on the opposite side, and vice versa.
The carbs had to be set to run rich through most of the power band to avoid running too lean at the RPMs where the ram effect kicked in--not very good for FE .
