I tried to attache pictures but I keep getting a pop up that doing that would exceed my limits, so I will try without photo. In the center of the intake under the carberator (side to side of engine), one side has a small muchroom shaped vent. It just pulls off. The opposite side has a little hole, but nothing in it.

I am in the process of eliminating road draft tube and going with pvc valve in the back of the valley pan to a block that fits between the carb and intake. I am also upgrading the distributer to a newer version (C3TF 121127 3ED Ford). I am going to install a new carberator but do not know if I will go with manual or electric choke, most likely electric.

My question is what is the mushroom vent for (Driver side) and the open hole (Passenger side)?

Just want know before I paint up the intake.

Is there problem with the software posting pictures or do I have to downsize them to post from my compter?
