These Holley Gen 3 Ultra Dominator carburetors feature a brand new main body, brand new state-of-the-art calibrations, high-volume HP fuel bowls, and sizes up to 1,475 cfm! The new patent-pending GEN 3 main body is 5/16 in. taller than the previous generation, which is the new height allowed for larger radius air entries that were optimized using Computational Fluid Dynamics (CFD) software to deliver smoother flow into new fully machined, big-bore venturi. Added to the new main body are the improved 6061-T6 billet aluminum metering blocks. They offer improved durability, true gasket sealing (sealing surface integrity), and are bright dipped anodized for good looks and corrosion protection. The metering blocks are fully adjustable (emulsion bleeds, power valve channel restrictors, and idle feed restrictors). The power valve channel restrictors are now machined lower in the metering blocks for improved fuel delivery to the power valve circuit, the accelerator pump channel is internally drilled, eliminating the need for an external plug, and excess material has been removed for increased fuel capacity. The new snap-in-place bowl vent whistle makes removal and/or replacement easier. The Holley Gen 3 Ultra Dominator carburetors include Holley HP fuel bowls that have been completely redesigned from the ground up for racing. With 20 percent more fuel capacity vs. a traditional V-bowl, they eliminate fuel starvation and provide consistent air/fuel ratios. Also, internal baffling helps to control fuel slosh and minimize float level fluctuations in hard launching or cornering situations, and the fuel shelf is positioned below the needle and seat to greatly minimize fuel aeration and promote more consistent metering. There is a fuel trough designed into the floor of the bowl to route fuel flow directly to the jets and assist in keeping the jets covered by fuel. Clear sight windows are on both sides of the bowls for easy and safe fuel level adjustments, and a built-in drain plug in the front center of the bowl provides easy access to empty the contents of bowl. Their contoured entry provides smooth fuel flow directly to the needle and seat. The HP fuel bowls also have material added in key areas (the needle and seat, fuel inlet, and sight window areas) for added strength in demanding race environments and can be plumbed from either side.

Holley Gen 3 Ultra Dominator carburetors' additional features include:

* All-new calibrations optimized for today's larger engines and new fuels
* Fully machined from venturi throat to throttle bore for predictable and repeatable performance
* Designed for use on drag race, Pro Street, or any high-horsepower engines
* All-aluminum construction saves 3.8 lbs. over original models (28 percent weight savings)
* Integrated idle bypass valve allows for adjustment of idle, while maintaining correct throttle plate to transfer slot relationship
* Factory-ready TPS mounting points for use with data acquisition systems
* Fully adjustable stainless steel external linkage can be adjusted for 1:1 progressive or soft progressive throttle activation
* No linkage parts under the carburetor
* 12-hole billet booster inserts for superior atomization and crisp throttle response
* Knurled (hand-adjustable) primary and secondary curb idle screws allow for easy idle adjustment without the use of tools
* Contoured hex head squirter screws for streamlined airflow
* Dual 50cc accelerator pumps
