Since I did not no the answer to the question ( First Annular booster Holley carb? ) Nick_nl was correct the 4010 holley , but some of us don't consider this a traditional Holley carb.
GTO Geoff mentioned Mike Urich so I looked in an old Holley 4150 &4160 Handbook by Mike Urich and this is what he had to say.
" In 1980 Holley introduced three new 4150 double pumpers utilizing a booster concept known for some time but never before used in performance carburetors. The concept is annular discharge."
"These carburetors have no choke mechanism and are intended strictly for competition in single or dual carburetor applications. Numbers are 0-9379, 0-9380 and 0-9381, with capabilities of 750, 850 and 830 cfm respectively."
So it was not the Dominator.

This is probably one of the first ( aftermarket ) Dominator carbs. List 6214. Notice, no annular boosters
