RB,
Once again your ignorance shows in post 69. Many Webers were fitted as production carbs, on intakes that had plenums, one carb feeding multiple cylinders.
The scenario I quoted in post #64 had MORE plenum volume, not less, so I do not know where the NONSENSE about behaving like IR carbs for this set up comes in. What the engine saw was 4 throttle bores, of equal size, no different to say a 750 Holley.
