For over 20 years, I ran a set of 3 Zenith 8810-B side draft carburetors/homemade intake on a moderately built '57 235. They were tunable and very dependable. With progressive linkage, they provided excellent response and reasonable mileage. When I sold the '57 in the '70s, I kept the carburetors.
In 2002, when I attempted to buy rebuild kits for the Zeniths, they were impossible to find, so I gave them away. I would have loved to put two of them on my 181 Mercruiser-powered Model A, but settled for a pair of Tom Langdon's Carter/Webber progressive two-barrel carbs.....which has proven to be an excellent choice.
