Well, depends on what year. The Rochester Quadrajet was used for a long time, but that won't answer your question. The Q-jet is an air valve, which means that it flows only what the engine wants, up to a max of 750 cfm (the 850cfm Q-jet was not used on the marine SBC to my knowledge). If you are looking for a Holley or some such, I would stick with 750 at the low end. Chevy Hi-performance Mag had an interesting article recently on carb size on a SBC and you'd be surprised to see how well larger carbs did. Those engines weren't torquey marine engines though.
