Bobby, before you pluck down the money for the Eaton, check out the Whipple/KenneBell/Lysholm. In the last 5.0-Mustang mag (sometimes I fall back to old habits, sorry.... :) ), there was an advertisement for a KenneBell setup as a direct replacement for the Eaton ( there was some factory offer with a Eaton charger, probably from the Motorsports department...), which claims more power/efficiency with the same setup (bolt in...) I know that the Whipple is pricier than the Eaton, but not that much!
