Hi Joey,

Big carburetor throats give you poor flow sensing at lower throttle
openings, which means you're going to have issues with around town
drivability. That's the whole reason why four-barrel carbs have primary and
secondary venturis and throttle plates.

A 390 or 465 CFM four-barrel with vacuum secondary actuation will give you
crisp response at any throttle opening. A 390 CFM two-barrel is going to be
boggy unless you're at higher RPM to start with.
