Holley Gen 3 Ultra Dominator Carburetors

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.
