The first Doninator I saw on a car was a 454 and it had a dual plane intake on it. I think it was almost 2 tenths faster on the Dominator.
Back in the mid 1980’s and into the 1990’s I saw dozens of Dominators on dual plane intakes.
When there were no throttle stops or junk like that, to run a “super” class they would limit the power some and use a dual plane intake.
Now it’s nothing to see a 180 MPH Super Gas car.
