NEW Patent Pending Gen 3 Main-Body that is 5/16'' taller than previous designs allowing new larger radiused air entries which deliver a smoother air flow into big bore venturi that are fully machined. The new inlet and venturi were designed using leading edge Computational Fluid Dynamics (CFD) to optimize the flow capabilities.
NEW Holley HP Fuel Bowl Design that has been completely redesigned from the ground up for racing with 20% more fuel capacity vs. a traditional v-bowl eliminates fuel starvation and provides consistent air/fuel ratios. Internal baffling to help control fuel slosh and minimize float level fluctuations in hard launching or cornering situations. Fuel shelf below the needle and seat to greatly minimize fuel aeration and promote more consistent metering. Fuel trough designed into floor of bowl to route fuel flow directly to the jets and assist in keeping jets covered by fuel. Clear sight windows on both sides of bowls for easy and safe fuel level adjustments. -08AN (o-ringed) inlet threads offer a large variety of plumbing options (come standard with -08AN o-ring to -06AN male adapter and -08AN plug). Can be plumbed from either side. Material added in key areas (needle & seat area, fuel inlet, sight window area) for added strength in a demanding race environment.
6061T6 Billet Aluminum Metering Blocks offer improved durability, true gasket sealing surface integrity, bright dipped anodized for good looks and corrosion protection. Fully adjustable with emulsion bleeds, idle feed restrictors and power valve channel restrictors now machined in lower metering block for improved fuel delivery to power valve circuit. Accelerator pump channel internally drilled eliminating the need for an external plug. Excess material removed for increased fuel capacity. New snap in place bowl vent whistle makes removal and/or replacement easier.

What Are Holley Gen 3 Ultra Dominator Carburetors Common Pros and Cons?
The Gen 3 line of Holley Dominator carburetors has improved features over previous generations. These include an improved main body, fuel bowls, calibrations, and metering blocks. Because of this attention to detail and extensive research and design process, these carburetors can be more expensive than other options available. However, the performance increases make up for the difference in your investment.
Which Holley Gen 3 Ultra Dominator Carburetors Are Best?
When choosing a Holley Dominator carburetor in the Gen 3 Ultra line, the first step is confirming the correct CFM size. This is based on the engine displacement, maximum rpm reached / redline, and application. Next, choose either a 2-circuit (for smaller engines and street use) or 3-circuit design (runs rich at idle and is ideal for Powerglide transmission drag racing as well as large race engines) and if doing a dual carb setup, choose the specific carb for it. Finally, choose the finish for the carburetor.
How Much Do Holley Gen 3 Ultra Dominator Carburetors Cost?
The price for Holley Gen 3 Ultra Dominator carburetors begins at the $1,300 range and goes up to over $1,800, depending on the CFM size and options. The Holley Gen 3 Ultra Dominator carburetor 0-80903, for example, is available between $1350 and $1400.
