Block off the power valves. With that much carburetion, you'll never develop enough manifold vacuum to keep them closed, so the size of the main jets, or other means of mixture control will be irrelevant. Then the engine will backfire, stumble, hesitate, and otherwise be difficult to run at anything other than a steady cruise on a straight and level road, but you'll still have that dual carb eye candy to look at. Alternative- - - - -find two small Carter carbs for a CJ-2 Jeep 4 cylinder engine and run them instead of the Rochester B's. Then you'll only be slightly overcarbureted instead of having the equivalent of two toilets flushing gas into your engine.
