Holley Ultra HP Aluminum Carburetors

How to Make the Best, Better!
The Holley HP™ carburetors have been the standard in racing carburetors for nearly two decades! So how do you make them better? You make the new Holley Ultra HP Aluminum Carburetors 38% lighter, increase the fuel capacity by 20% and add 30 other new features! They're available in our all-new Hard Core Gray™ hard coat anodized finish with Black™ billet for improved corrosion protection. They're also available in natural tumble-polished aluminum with your choice of Black™ or Red™ metering blocks and base plate. These carburetors are available in 600, 650, 750, 850, and True 950-CFM sizes!

    6061T6 Billet aluminum metering blocks
  • Improved durability, true gasket sealing (sealing surface integrity), bright dipped anodized for good looks and corrosion protection
  • Fully adjustable (emulsion bleeds, power valve channel restrictors & idle feed restrictors). Power valve channel restrictors now machined lower in metering block for improved fuel delivery to power valve circuit
  • Accelerator pump channel now internally drilled eliminating need for external plug
  • Excess material removed for improved fuel capacity
  • Integrated pry-point assists in disassembly from fuel bowl and mainbody preventing damage to gaskets and gasket surfaces
  • New snap in place bowl vent whistle makes removal and/or replacement easier

    6061T6 Billet aluminum base plates
  • Improved durability, true gasket sealing, bright dipped anodized for good looks and corrosion protection
  • Elongated (dual pattern) mounting holes allow fitment on intakes with square flange (Holley 4150™ style) or large flange (Holley Dominator® style)
  • Dedicated race-only throttle lever with all unnecessary street attachment points & tangs removed
  • 950 CFM throttle shaft comes slabbed and undercut for improved airflow
  • Stainless steel adjustable secondary link. Provides choice of 1:1 or progressive secondary throttle actuation for ultimate control of secondary opening rate
  • Knurled (hand adjustable) primary and secondary curb idle screws allow for easy idle adjustment without the use of tools
  • Primary throttle shaft capped to prevent entry of debris & contaminates
  • Factory machined accessory mounting hole for easy addition of adjustable throttle stop
  • Throttle body and new secondary pump cam lever designed to provide positive throttle stop on secondary side. Delivers safe & reliable 90° opening and return of throttle plates while ensuring maximum airflow
  • Baseplate designed with a boss that can be consumer machined for vacuum source

    All new fuel bowl design
  • Completely redesigned from the ground up for racing
  • 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 Pyrex® sight windows on both sides of bowls for easy and safe fuel level adjustments
  • (A) Built in drain plug in front center of bowl provides easy access to empty contents of bowl
  • (B) Contoured entry provides smooth fuel flow directly to needle & seat
  • -8AN (o-ringed) inlet threads offer a large variety of plumbing options (come standard with -8AN o-ring to -6AN male adapter and -8AN plug). Can be plumbed from either side
  • Material added in key areas (needle & seat area, fuel inlet, sight window area) for added strength in the demanding race environment
  • Note: New lengthened fuel line required due to increased length of bowls

    Updated mainbody design
  • Air bleeds moved outward to allow a smoother transition of airflow from the top of the carburetor into the venturii
  • Integrated idle bypass valve eliminates the need for holes in throttle plates and allows for proper adjustment of idle while maintaining correct throttle plate to transfer slot relationship. H elps maintain good idle control when using radical camshafts.
  • All unnecessary mounting bosses removed for a smoother, cleaner appearance
  • Contoured hex head squirter screws for streamlined airflow
  • Cast in Holley HP logo for easy identification by race sanctioning bodies
