Help me ID my carb

71 swinger 318. bone stock. im replacing my fuel tank, sending unit and rebuilding the carb. i'd rather throw an intake and a 4bbl on it but i just want to get it running right first. and the rebuild kit is less than 20 bucks. so that being said, i went to the parts store and they have 3 different kits to choose from. how can i tell which carb i have? there are some numbers on the pass side of the carb and a symbol on the front which i dont recognize. anyone? anyone wanna hook me up with a nice intake cheap?
