  • AFB question ???

    Just acquired a 4 bbl manifold , carb and air cleaner off a ' 64 Lark, today. When I got it home I checked all the numbers out and the carb # isn't in the parts book but I find it on a Studebaker carb listing I have and it shows that # in this listing. The # is 3506S with A3 under it . Now I have another ' 64 set up and the carb # is 3726S and that one is in the book . Can anyone tell me what the difference is between these two carbs ....if any ? There doesn't appear to be any difference looking at them.

            JP....I looked in the back section under jet thrust part numbers and the 3506S carb # isn't mentioned there either. You sure its a R1 carb ?
