I would say a 500 CFM but no bigger than a 600 CFM. I don't know if you are looking for an answer on flow (CFM) or just a generic answer like "two barrel" or "four barrel". As I recall, in 1963 the 283 was only offered with a two barrel carburetor. I believe the rated horsepower was 195. The carburetor was either a Rochester or a Carter. Flow was likely not more than 400CFM.
600 cfm will be enough for that engine.
depends on the application, but anywhere from 600 cfm up to 850 cfm is common. Carburetor manufacturers provide a formula for this calculation.
depends on the use and internal components of the engine.
