I bought a bunch of NOS BBD kits and got several "toilet bowl" BBD kits.

What kind of CFM did the 383 BBD's flow?

Somewhere in the 350cfm range... there is another size BBD I had not seen before, until I traded my buddy a useable Stromberg from a '67-383 for his BBD off a 413-2V Dodge 600 Dump Truck...

Bigger than the 1 1/2" ones?
