I can assure you that a 287 CFM 2V will be flowing at least 100% VE. How can I say that? If everything is right in the combo, the engine WILL be pulling vacuum long before it gets to the finish line. OBTW, try explaining that to the man designing your cam.

What Billy said plus this
carb is rated 287,on dyno with air turbine will pull more than 287 cfm.
