Holley 6425 650 CFM 2 barrel

Has anybody ever run the Holley 6425, 650 CFM 2 barrel carb on the street? How are they at part throttle? How about full throttle?

I have seen articles saying that they have good bottom almost as good as the 4412, 500 CFM. A Holley book that I have says not to use them below 4000 RPM under power. Anybody experienced or heard otherwise?
