I would talk to a carb expert first about your current carb, before switching. You'll usually get much better throttle response from a vacuum secondary carb than a double pumper. Putting another carb on might help, but you'd only be putting on a carb that setup closer to what your car needs, not that it was "better" than what you had.

I just spent 2 weeks custom tuning my carb on my CSX. It was a PITA, but it needed a lot of adjustment work for my engine. Now the car runs awesome.
