This was more of a "bench racing" thing. I do not have any immediate plans to change my set up of a Offy intake and 390/stove bolt header.
I wish that the made a twin two intake for 2GC like this one for two ones

The only adapter I have found for the 2GC carbs is a trans dapt piece that mounts the carb sideways, I would not like that

I would think that two 2GC would make a great set (set up 1:1) up for a moderate street strip set up for a stick car.
