Holley makes one, the 9379 Competition Series.

The 9380 is the annual 850, and the 9381 is the annual 830. The competition series come with choke horns in place, but no actual choke. If its annular but does not have adjustable air bleeds its probably a good bet its the old Competition series (which you can still buy new).
