Holley List 1850 rebuild or noooo?

What is the ultimate goal for the car/engine? Power, economy? And what kind of mild cam are you using? A torque cam or a higher duration HP cam? IMO, I would consider this a decent carb for economy (maybe a bit on the small side to let the engine breath), and a torque cam. I had really good results with a smaller engine and this sized carb.
