When asking ecm questions

[CSH-HQ]

Again, the Holley TB's are not flowed, but rather a mickey mouse formula 
applied to the amount of fuel available (IMHO)....
  All the TB use the same size butterfies with the difference in the injectors.
  As I recall all four butterflies are 1  11/16", figure the area out, and 
compare that to two 2" butterflies.  By the time you allow for laminar flow, 
I'll bet ya your close, or to 56mm
Soooo, use to BBC TB's and be sone with it (dual carb man)
