The fuel bowls have 20% more capacity than those on the standard HP carburetor, greatly reducing the risk of fuel starvation and stabilizing air fuel ratios. There’s also internal baffling in the bowls to reduce fuel slosh under hard g-loads. There is a fuel shelf below the needle and seat to minimize aeration, and a fuel trough has been built into the bottom of the bowl to route fuel directly to the jets to keep them covered — again allowing for more stable air fuel ratios.
It is also available in GAS. The HP Carburetor below has 20% more fuel capacity vs a traditional v-bowl, 97% aluminum construction translates to 38% weight savings for the new carb. The carbs are available in 600, 650,750, 850 and true 950 CFM
For an excellent review and how to tune this Carburetor ClickMe to see article from DragZine. This article compares the HP 850 and 950 to the stock carb and each other on a 427 cu in. Tease: What we ultimately found was that this Holley HP 850 carburetor made its best power right at a 13:1 air/fuel ratio. This gave us that aforementioned 1,100 rpm increase in the engine’s available power band as well as the 60 hp peak increase we saw as well.

Holley implemented a host of changes and upgrades for the Gen 3, completely redesigning the main body and developing an all-new, high-capacity fuel bowl. “We used extensive CFD analysis to design the main body,” says Tichenor, noting the main body is 5/16-inch taller than the previous generation Dominator. The higher platform allows for a larger, more contoured radius on the air entries.
Other improvements to the main body include: 1) Integrated idle-bypass valve that allows idle adjustment without disrupting the relationship between the throttle plate and transfer slot, 2) 12-hole billet booster inserts for improved atomization, 3) Extended air-cleaner flange to accommodate new air-scoop adapters, 4) Contoured hex-head squirter screws to streamline air flow, 5) adjustable stainless-steel linkage and knurled idle screws.
Billet aluminum metering blocks are used for improved gasket sealing, corrosion protection and cleaner appearance.
The new fuel bowls offer 20 percent more capacity to help eliminate starvation, but there are also numerous other features to provide consistent fuel delivery: 1) Fuel shelf is located below needle and seat to minimize aeration, 2) Internal baffles control fuel slosh and minimize float-level fluctuations, 3) Fuel trough is designed into the floor of the bowl to route fuel flow directly to the jets, 4) Clear sight windows for fuel-level adjustments, 5) Drain plug in the front center of the bowl for easy jet changes.
