Any input on this carb?

Simple rule of thumb here. Automatic=vacuum secondary. Maunal=double pumper. There are exceptions, but the rule will serve you well. The 750 Dominator is a THREE circuit carburetor. The three circuit carbs will run very rich without expensive tuning. A 3310 750 will probably be perfect for you outta the box.

I dont agree with that at all. A 750 will run perfect on a medium (unsure what level that is) built 360. Vacuum carbs are for stock cars with too low stall speed and highway gears. Any car with gear and a remotely loose converter will like a double pumper. The Holley 750 dominator is a 750HP in disguise for the car show crowd who wants the flash of a Dominator but run like a 750. The 3 circuit carbs run well on the street, the two circuit have a huge problem at part throttle where the intermediate circuit should be, but it doesnt exist on a 2 circuit. That 750 Dominator would actually run well on his 360 even though it probably doesn't sound like it needs one.
