Personally I prefer the OEM carb setup. For one thing with four carbs you can balance the engine better which is specially nice if your compression between cylinders vary. With a single carb you cannot, you can only attain a general adjustment across the board. If a carb fails you can still run on the other three to get somewhere other than the side of the road. Finally looking at the setup you would also reduce air volume though I guess air velocity would increase, maybe. There is a reason why in the muscle car hay day we replaced 2 barrel carbs with four barrel or even 6 packs. JMHO.
