Info

Holley HP™ four barrel Carburetors have been the standard in racing carburetors for nearly two decades. So how do you make them better? You make them 38% lighter, increase the fuel capacity by 20% and add 30 other new features! They're available in an all–new Hard Core Gray™ hard coat anodized finish with Black™ billet for superior corrosion protection.

New Features! (LINK)

Note: Fuel inlets are spaced 9.75" on center which will require a lengthened fuel line / fuel log arrangement. Fuel bowl inlets feature -8 AN O-ring port fittings to allow for a large variety of plumbing options. Fuel bowl can be plumbed from either side.

Notes

  • Aluminum Construction
    • Saves 4.5 lbs - 38%
  • Billet Aluminum Metering Blocks
    • 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
  • Billet Aluminum Base Plates
    • Stainless steel adjustable secondary link
    • Provides choice of 1:1 or progressive secondary throttle actuation for ultimate control of secondary opening rate
  • All New Fuel Bowl Design
    • 20% more fuel capacity vs. a traditional v-bowl eliminates fuel starvation and provides consistent air/fuel ratios
  • Updated Main Body Design
    • 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
Some parts are not legal for use in California or other states with similar laws/regulations
