No doubt about it. A single four will give better over all performance and is much easier to "dial in" and maintain. MOST of the time it will provide as much HP\Torque as two fours will provide (often it will provide MORE). To much CFM on carbs is a VERY common problem, more\bigger is NOT better! You have to have a pretty radical motor to gain any HP advantage from two fours over a single four.

That said: Two four barrels look WAY cooler than a single four! And a set of Webers look even cooler than that.
