I believe the 4010 came out in 1986. Kind of the forgotten holley. It was very similar to the ford 4100 carb of the 60s.
So other than the 4010, what was the first annular ( traditional) holley

In 1977 David Vizard asked Mike Urich ( who was Holley's chief engineer ) what research Holley had done on fuel atomization . He said they had done no direct investigations into what made for good atomization and to what degree it affected part and full throttle performance.

The Holley 4500 (not yet named 'Dominator') was built in 1968 for big-block Nascar engines. It had annular boosters and debuted in the 1969 Daytona 500.
Autolite invented the annular booster in the late 1950's.
