Holley Dominator® Carburetors
were designed specifically for making Top End Horsepower and Torque in High End Racing Engines. The new Ultra Dominators keep that same mentality alive with even more features.
The new Ultra Dominators feature all aluminum construction which saves 3.8lbs of the top of the engine. The Ultra Dominators feature 6061–T6 billet metering blocks with changeable emulsion, idle feed, and power valve restrictions, a fully hand polished top and venturii for maximum airflow and less air turbulence, Teflon coated slabbed throttle shafts with low profile, button head screws mated to lightweight anodized aluminum throttle plates improve airflow, Fully adjustable external linkage provides 1:1, progressive, or soft progressive throttle activation, 12 hole anodized billet booster inserts for superior fuel atomization, and aluminum dual inlet fuel bowls with built in clear sight glasses are just a few of the features on the new Ultra Dominator.
The clean, polished look coupled with Red, or Black metering blocks, booster inserts and throttle plates will certainly set your ride apart whether you are at a show or the track.
Don't trust your performance to just anyone, Holley is the only Modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's.
