Older Dominators can be made to run quite well. And I am partial to a 2 circuit for almost any application. I have run a 2 circuit setup on a 2.25 throttle blade 2.050 venturi carb that flows about 1740 CFM on my small block with no need for an intemediate circuit. A local guy here runs two 2 circuit 1050's on a 600+" engine that runs 4.40's in a dragster in the 1/8. The 3rd or intermediate circuit was designed for IR intakes where cylinder pulsing is not dampened by a plenum, these pulses can disrupt the flow from the boosters at low speeds. 4 and 6 cylinder engines may benefit as well because the pulses are stronger even with a plenum.
What model number is the old Dominator, and the model number on the newer one?
