I'm looking to upgrade my 63 Polara 500's 2 barrel BBD (383, auto) to a Carter AFB. In a perfect world I'd like a 3437 as this would be the correct carb. Does anyone know where I can get one? Are there other AFB's that are compatible? I see lots on ebay with electric choke; I'm assuming I need automatic choke. How about an L3 4200s? Was this a special police package? How about a 3460 from a '63 Vette? Anything else? Thanks. - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge) '63 Polara 500 (383) '65 Belvedere I (Street Wedge) '71 Bronco
