^^^ Yup.
It's something of a generalization, but for street use, a smaller carb will work better than a big carb, especially on a small engine like a 318.
Velocity vs volume, and better vacuum signal as a result.
Airflow of the heads also figures in.
Note that the 6-bbl/Six-Pack cars generally ran with the small center carb for most street duty.
Agree with the T-quad, kinda best of both worlds on the street, been there.
2nd best I think would be an Eddy AVS2, I really like mine.
For most 318s, 600-650 CFM is fine.
