Weiand Action Plus vs Edelbrock RPM

Well, It went from a 14.14 down to a 14.11. Hard to say weather conditions. I know today wasn't good air. Typical this time of year. MPH was .5 slower (97.2 down to 96.77), 60 ft time went from 2.05 to 2.01. Both intakes gained a solid 20 mph from the 1/8 to finish.
Bottom line, I think there is a "slight" gain, but I think this shows it's not necessary to spend money to go from an Action Plus to a RPM on a real mild car. Obviously, the more "upgrades" to the car, the more it would favor the RPM.
