  • Dual 30cc accelerator pumps provide additional fuel during hard acceleration
  • Contoured venturi inlet balances airflow for increased horsepower output
  • Stainless steel throttle plates resist wear and corrosion
  • Gold dichromate finish provides superior corrosion resistance and classic appearance

Tuning and Adjustability:

  • Screw-in air bleeds allow precision tuning without disassembly
  • 4-corner idle system provides precise control over idle mixture and quality
  • Includes notched float and jet extensions for improved fuel delivery
  • Dual-feed fuel inlet design ensures constant high-volume fuel supply

Installation and Compatibility:

  • Calibrated for pump gasoline with standard jetting
  • Compatible with GM, Chrysler, and Ford automatic transmission kickdown linkage (additional parts may be required)
  • 100% wet-flow tested by Holley technicians to ensure ready-to-run performance
