carb for mini blower

Is this a street or strip application?
Holley has boost referenced power valves on their blower carbs.
For a street/ strip application use Holley 80573S it has a choke. $600
For a wild street and intense strip application use the Holley HP 80576S $689 (HP carbs are for an all out performance engine/application) choke horn milled off
Both are 750CFM

This is not a blow thru centrifugal system, so you do not need a blow thru carb and dont use a boost referenced fuel regulator.

Set the total timing to 28° for initial tuning
