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

local engine builder had spun both intakes out of the box on the dyno on the same combos and has made more power with the Eddy intake every time. I have seen some stuff make more power on the dyno, yet the other combo got down the track better faster etc. Just goes to show you never know till you go to the track.
