What else is done to the car? If it's stock, I'm afraid changing the carb is money down the drain. That should be one of the last things you change. They can be modified to flow ~750 cfm with crisp throttle response.

You've already got the right carb. Check out the tech articles (linked on the board home page) for what will make it perform better.
You car is being held back by exhaust, air cleaner, cam, ignition, and heads, in that order. Spend your money there if you want better performance.
