1968 340 AVS 4425S carb replacement

Hows it going guys, I am looking on a replacement carb for a 1968 gts 340 auto. What would be the best/correct bolt on carb with non electric choke (has the thermostat choke in the intake) for the car. I do know that Edelbrock makes replacement avs carbs, but would be the correct cfm for the car?
Any help would be appreciated
Thank you
