Weiand Action Plus vs Edelbrock RPM

Quick seat-of-the-pants test revealed nothing that I could tell. Granite, I don't drive the car very much, but I have a spot on a back road and it did the exact same mph as before. Of course, the ET slip will have the final say, and keeping in mind that each day at the track can very a tenth due to the weather, but we will see. Don't know when my next opportunity to go to the track will be, but i'll go there soon as I can.
