What exactly are you trying to do????

I suspect from the sounds of it your either setting up an old 6 duce intake (like I'll be running on one of my Hemi's) or 2 tri-powers. What manifold/engine are you building?

The 2G/2GC/2GV are basically the same carb. If this is for a multiple carb system, set up properly your only going to want a choke one one carb (tri-power) or the 2 center carbs on on a 6 duce set up. Regardless of the carbs you are using, you should be removing the choke on the rest.
