Which Carb Type?

We have a 1970 Dart Swinger 340 4spd. Only mods is electronic ignition with a mallory box, Headers and edelbrock street intake and possible a cam? (engine was claimed to be stock but we have an idle vac of 14 in/hg).

We are looking into a new carb after not being able to get ours set right. The car is used as a cruiser that may occasional get honked on(wink, wink, this is the owners son typing).

We are thinking a 600-700 CFM Range. Everyone one has different opinions on what brand, but they either race or never owned a mopar.

Anybody have an idea or experience with a certian carb that uses the car for cruising?
