Getting enough fuel is not the problem. Getting the right amount of the best mixture of air and fuel is the goal. That often calls for bigger or more carbs but whatever you have must be set up for your use. A 4 barrel is a good choice for ease because it has less linkage to adjust and most have lots of jetting options. Duel singles runs well and looks way cooler than a 4 bbl. If you can keep your foot out of it you can actually improve milage or at least not hurt it much. Beater
