Earlier versions used the Carter WCFB four barrel rated at roughly 425 cfm or something along those lines; in '60 or '61, they switched to the AFB. Today, for a relatively stock 318, you'll want the Edelbrock 500 cfm; go 600 cfm for a hot cam and other mods, but remember, it's all too easy to over-carburate!
Remember, too, that earlier manifolds designed for the Carter WCFB had a smaller based made for that smaller carb; you'll need an adapter to fit the later AFB or the essentially similar Edelbrock. Strongly suggest going with a manual choke if you choose the Edelbrock; much, much better control with foolproof operation.
