Carb

Does anyone know the cfm of the 440 avs carb? Getting ideas for my mostly street 451/727/A body automatic. Thinking about a 800 cfm thermoquad as best all around carb. Thanks

The 69 440 HP AVS #4640 is 750 CFM all the rest are smaller I think, this is the only AVS with big primary throttle plates

I’ve got a rebuilt 4640 if you’re looking for one.

If I recall correctly Carter rated their carbs differently from Holleys.

All HP 440 AVS’s have the large primaries but in ‘69 the diameter of the accelerator pump was increased.
