Features

    American Made - Materials and Assembly
    Aluminum Construction (saves 4.5 lbs - 38% weight savings)

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 4500™ 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
    Built in drain plug in front center of bowl provides easy access to empty contents of bowl
    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 (see Holley p/n 34-42, 34-43, 34-44 or Earl’s p/n AT104195ERL, AT104295ERL & AT104286ERL)

UPDATED MAIN BODY 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. Helps 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
    Available in 600, 650, 750, 850 and True 950 CFM
    Available tumble polished with Red™ or Black™ billet.
    Available in all new Hard Core Gray™ hard coat anodized with Black™ billet. First-ever hard coat anodizing on fuel bowls and mainbody - actually penetrates the aluminum for superior corrosion protection.
    Adjustable Throttle Stop bracket and WOT Microswitch brackets available
    Due to hard coat anodizing process on cast aluminum, some color variation may be visible on Hard Core Gray™ carbs.
