Old Man Dirt Says: A small four barrel. While two barrels are good for some things, fuel economy is not one of them, Going to a four barrel will improve fuel economy as long as you stay out or the "back two". You don't have to replace the manifold, spacers can be found to adapt a four barrel to your existing one at places like summit racing, or speed way motors.
