Not Ranked
Large runners are not everything guys, velocity is king. Depending on your combination, and intended operating RPM, smaller runners can make more power, especially if you are not spinning it up to 8,000 RPM. Talk to your engine machinist/builder for advice, experience really counts when picking a combination of parts.
