This results from their single-plane configuration, with its unique split-plenum chamber and tuned intake runners. That combination delivers the fuel-air charge evenly to all cylinders for more power without flat spots. Edelbrock Performer series and Carter AFB carburetors are recommended. Some applications cannot mount Holleys in any manner, or clear HEI.
