This is fine - if you have a car that runs only on weekends, and a quarter mile at a time. Most folks run their car to work, to the store with stop and go driving. This means compromise for driveability, fuel mileage and just plain driving enjoyment. A mild 331 CID Chevy(or any other engine) with a flush toilet size carb is NOT fun to drive. Bigger is not always better. Been there - done that with 750/780CFM 3310s and 950 CFM three barrels on BB Fords to name a couple of toilet sized carbs
