Carter YF carbs if you want to run dual singles. The W-1 may also be an alternative but I have never run those carbs only the YF, YH side draft and Rochesters (which I would not recommend). Another alternative, use the small carter/Weber carbs that tom Langdon sells over at stovebolt engine company. These would be preferable in my view. You will have to use adapters because those carbs are two bbl progressive carbs, but they are smaller then the Holly/Weber 5200 pinto carbs. Nice small primaries, larger secondaries. They run really well as pairs right out of the box Without much fussing around. If it was a 235, you could used the carter/Weber or the Holley/Weber, I would go with 1974 ford pinto holly/Webers, the fuel inlet is threaded.
