Absolutely! A properly working carb should respond instantly to all your throttle commands.

You did not mention what is under the carb and as I'm sure you know that is equally important. I'm guessing it's a small block. The 750 Holley is maybe too big for it, but in general a properly working vacuum secondary carb is great on the street. The fact that it was an oulder rebuilt Holley mat also be a problem as the throttle plate and rods can wear and begin leaking when they get older.

Fuel injection is great too, probably outperfroming a carb in every way, again when properly tuned. The thing I don't like about them is cost and clutter. All the wires and control boxes etc really muddle things up under hood and dash IMO ............
