I have a Holley 650 on a 302 and it runs great. No hesitations or flat spots, idles nicely with well balanced performance. Be sure the ignition system is in good order and the timing is set correctly, then the carb can be tuned. You can make the adjustments yourself, but I had a well respected local shop make the final adjustments and it was money well spent. I am very happy with how the car runs.

It's easy to have more carburetor than the motor can handle, more gas does not always mean more power, many times it's the opposite. A properly setup fuel injection system can get you even more power and drivability, but some folks prefer a well setup old school carb.
