"Popular"- - - - -yes. "Right"- - - - -NO! No matter how many, or what brand of carburetor you choose, multiple carbs on a stovebolt engine only accomplish one thing. That's to impress the mouth-breathers at a show & shine event, the ones who don't have any idea about physics. A stovebolt cylinder head simply can't breathe well enough to take advantage of an increase in carburetion (or exhaust) airflow. It's like joining two pieces of heavy tow chain with a paper clip. A good single Carter YF carburetor calibrated for an American Motors/Jeep 232 or 258 cubic inch six will provide all the fuel/air mixture a 235 can handle, and unless you're planning to run a 261 engine wide open all day every day in a big truck, hauling a max load of cargo (or a big overload), it will also work well on that engine. 261s are scarce and somewhat e$$$$pensive, but they seem to be the holy grail for folks who want to stick to a "stock-appearing" engine in a stovebolt pickup. They were used from 1954-62 in the bigger stovebolts- - - -1 ton and up, school buses, etc. The same displacement engine, with a hydraulic cam, was used in "Pontiac" cars in Canada during the same time frame.
