Need help - What size carb to go with?

I currently have a 2bbl carb set up on my 71 350, it runs out nicely but seems to be sluggish on take off - I want to change the carb over to a 4bbl setup for better power/throttle response but not sure what size to go with. I want the truck to have nice throttle response and haul ass but I'm not trying to build a racer. I'm thinking a 600 to 650CFM. Gimmi some opinions please.
