750 cfm carter competition on a 360

I have a Carter competition 750cfm carburetor with mechanical secondaries, and a 360 bored .30 over, moderate purple cam estimated 300hp. Automatic a518 trans, 3.55 and 4.10 gears (3.55 currently in the car).

The car is 100% street rodder, is this carb to much for my setup?
Would vacuum secondaries be better because it's a street car?

What are your thoughts on a setup?
