Here is a google web page with engine cfm calculators.

I am guessing a 600 CFM carb will be fine.

Changed the thread title. A thread related title will get you more responses.

X2....A 1406 Edelbrock is the easiest to tune . Same carburetor as the old Carter AFB . Bought a kit for my buddy's 1406 yesterday . Application list includes AFB .
