How many CFM? '76 360 2bbl

The Holley 2barrel on 360 has a 1 5\8 throttle plates with a 1. 3\8. Venturi bore comes in a 435cfm. The same carb is used on 400 b. Engines
I always knew them being near 400 cfm, too much for the slant I had at the time.
Garrets list above my post is close to what I was told.
