steve langdon has new carbs for sale that are 2bbl, and over on inliners.org, a lot of the guys like them, there not a holley 2bbl, I think there his very own carb, and there price is right at just $65 bucks a peice they use a standard 2bbl flange and he sells the converters to go from a 2 bolt but you would need to convert that to a 3 bolt. I'v wondered about using the 1bbl Holleys that Ford used on the small 6's, there still available from holley remanufactured and some have automatic choke ( the 1 on mine has a factory Holley remanufactured sticker, and has an auto choke, works fine except the needle valve sticks because the car sat, carb&choke cleaner should clear that up )
