Intake mod?

Moper, some of the Edel. intakes have the cut in the divder, but not my S/B RPM. My LD-340 has it. I also have the LD340 with the MP book mods done to it. I want to try all 3 intakes at the track with various carbs on top just to see how it is and reacts, etc.......

one day, you all will know.

How does the LD340 compare to the rpm/rpm ag?
