Dual quad info

Makes complete sense. No luck with heims locally, so ordered 2 from Amazon. Christ HD didnt even have threaded rod 5/16-24.
Digging thru extra goodies I found the threaded end for kick down. May come in useful.
Gotta mount choke to mock up dual fuel inlet.
I would suggest that you try to set the carbs up to open progressive and use the back carb as primary. That way during the 80% of the time that you are just running on primaries on the primary carb, your "2 barrel" is in the middle of the manifold next to the cross over, not all the way in the front of the manifold.
