I have two Carter AFB carburetors that my book says fit 63 to 66 Buick. Can anyone tell me exactly what car and engine they fit? The numbers on the front passenger side baseplate are; 3633S and 3503SA Thanks
3503SA fits 1963 Wildcat, Electra, Riviera or LeSabre 401 or 425 3633S fits 1964 Wildcat, Electra, Riviera or LeSabre SW with 401 and AT During both 1963 and 64 these models could have come with a Rochester 4GC or the Carter AFB's that you have. John
Thank you John. I appreciate your response. This is a great site for Nailhead info. Keep up the good work guys.
