From testing both Chrysler and myself, the top of the
carb should be 3/4" below the bottom of the scoop for
best performance... if the carb is up in the air flow
its causing turbulence plus if its way up in the air
flow its making the air go into shear to get into the
carb .... if you want to do a cheapo wind tunnel test
tape 2"-3" long pieces of yarn to all different places
in the scoop and mount a camera to the hood so you
can record the action of the stings
