Having run Langdons Carter/Webers on my built 235 for almost 10,000 miles without any major adjustments since they came out of the box, I highly recommend them. However, aside from the fact that they give excellent, carefree performance, dual carbs are not going to give you any great noticeable "kick-in-the-pants" sensations when you put your foot down and open the mechanical secondaries. Granted, you eliminate all of the issues encountered with a wornout Rochester, but I'd have to say that the "visual" effect is paramount. Having run a single Holley/Weber on the same engine with just as good performance/fuel mileage, I think you need to consider the cost of a dual setup, the initial installation, and what you're trying to accomplish by adding duals.
IMO, running triple carbs on a 235 with the center carb blocked off, with the linkage and firewall/shift box/fender support rod clearance issues just seems like a waste of time and money.
