David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting
Was looking at an Air Gap 4 barrel intake manifold and noticed the "Texture" down at the bottom of the runs of the plenum.
This is the same thinking as Charles Servedio is doing in the bottom of the Single Plane 318 plenum with with the Clay Domes he is experimenting with what he calls the Golf Ball Surface texture to help keep the fuel in suspension and to help smooth out flow to the runners.
Experimenting, Experimenting
