Before you decide on the exact cfm carb you need, you might want to take into consideration the weight of the car, the size of the track and the minimum rpm the engine will see in the turns.

All else being equal, the heavier the car, the smaller the track and the lower the minimum rpm, the smaller the carb you'll need. Given your engine I'd consider 750 cfm to be the lower limit. If the reverse of the above is true then an 830 cfm unit might be more appropriate.

If you're on the fence flipping a coin, go with the smaller unit. You'll be happier in the long run.
