Small Block Weiand Action+ vs. Edelbrock RPM Air Gap ET/MPH Comparo

1/4 mile times today were an average of 11.81@111mph (3 back to back runs all within .02 of each other. The low and mid power of the Air Gap over the modified Action+ is very noticeable, and up top it also has a bit of an edge. In my case it was a good upgrade ootb, with room for some massaging. YMMV
