I run the 1407 manual choke 750cfm Edelbrock carb on my mildly built 360 Duster and it runs great. Fattened the primary rods alittle to lean it out, adjusted the mixture screws and bumped the intial timing up to 18 degrees.

Smokes the tires out of the hole anytime with NO BOG and drop the hammer at any speed with NO BOG! Gas mileage? who cares!

The float setting MUST be checked on even new carbs and fuel pressure is also critical like people have mentioned. I'll bet many times people blame hesitation on the carb when it's actually the timing or distributor that is the culprit.
