I'm putting together a little T-based sorta track roadster thang, and building a GM Quad 4 engine to power it--primarily 'cause it has: A. A Fronty/Rajo/Offyesque look to it; B. I can almost afford it... C. It will fit right in with the overall vibe I'm looking for. I'm thinkin' a pair of updrafts are almost mandatory--any suggestions? I have noticed that the T'n'A supply houses have new replacement Zeniths. Eddie
Carter BB-1s that were used on many C.O.E. trucks from the '40s through the '50s don't seem to be too hard to find.
There are LOTS of options, depending on: (A) how much you plan to actually drive it (B) quality of carburetor (C) "look" you are hoping to achieve (D) how long you want it to last (E) how much you want to spend The driveability of the updraft carburetor changed forever in the fall of 1931 when Stromberg introduced the SF and SFM series, and Zenith introduced the 63 and 263 series carburetors. Carter followed in 1932 with the BB-1 series, while an excellent carburetor series, not as wide a coverage as the aforementioned Stromberg or Zenith. If you wish to discuss the application, give me a call during my normal telephone hours. Along with answers to above questions; need engine CID and RPM (both normal cruise, and WOT). The mass (weight) of the target vehicle can be important, but since you posted a T roadster, will assume mass is not an issue. No obligation. Along with the five series mentioned above, Zenith has produced quite a few additional series with a target of agricultural / industrial applications. Holley also produced an agricultural carburetor. And then the Borg/Warner combine produced a number of series of aftermarket replacement "carbs" mostly marketed through companies such as Whitney, Warshawsky, and Western Auto. Jon
I have a Carter BB 245SD on my Model B banger, not had the car very long but it seems to work fine so far. I also have a Zenith 267 on my '28 Chevy Banger which is a huge improvement over the original type.
