I have run many 1406 carbs and am very happy with them. My 57 presently has a 1405 manual choke. A 600 CFM carb is more than enough carb for a 327 displacement. I have my 600 CFM carb on a 400 Pontiac Big Block and I would not go any larger. Keep what you have, if it runs well and is reliable to start and runs well at idle I would not change a thing.
