I bought a holley 500 Circle Track performance carb to run on my Street Stock. 358 500+ HP. Is the stock 30cc accelerator pump OK or should I replace it with a 50cc?

Leave the 30cc one in. The 50cc might sound better being bigger but it's best for a street driven car.
Actually some of the better high end 500 carbs use 50cc pumps. It depends on how it's calibrated. You're best suited to ask the builder which one you need.
