Holley 4500 1475 CFM 3 CIR - BLACK

The original Dominator® took carburetion to new heights back in 1969, designed specifically for the adrenaline-pumping world of NASCAR® racing. Fast forward to today, and we’re excited to introduce the Gen 3 Ultra Dominator, which represents the most significant evolution yet! With a fresh main body design, cutting-edge calibrations, and high-volume fuel bowls, this beauty boasts sizes up to 1475 CFM!

What’s new? The patent-pending GEN 3 main body is now 5/16" taller than its predecessor! This extra height allows for larger radius air entries, optimized using advanced Computational Fluid Dynamics (CFD) software to ensure a smooth flow into the newly machined, big bore venturi.

But that’s not all! The main body comes equipped with an integrated idle bypass valve, letting you make idle adjustments while keeping the throttle plate and transfer slot relationship just right. Plus, the extended air cleaner flange makes attaching an air scoop a breeze when you use the available air scoop adapter.

The Gen 3 is designed with high-capacity fuel bowls that hold 20% more fuel to prevent starvation. It also features an integrated fuel shelf to reduce aeration and internal baffling to manage fuel slosh effectively. You’ll appreciate the all-aluminum construction, 12-hole billet booster inserts, fully tunable billet metering blocks, adjustable external linkage, throttle position sensor mounting points, and knurled (hand adjustable) curb idle screws.

Every calibration has been rigorously dyno and track tested to ensure it delivers reliable performance!

Notes:

• New or modified fuel lines are necessary if you’re replacing an existing Holley Dominator 4500 series carburetor.
