Holley HP™ carburetors have been the standard in racing carburetors for nearly two decades. Powering the biggest names in NASCAR to the Saturday night racer, HP carburetors are the perfect choice for all types of motorsports.
Classic HP carburetors are available from 390 to 1000 CFM and feature a contoured venturii inlet for balanced air flow, screw in air bleeds for precision tuning capabilities, high flow metering blocks and Dominator style fuel bowls which allow pluming from either side for ease of installation.
Holley HP carburetors are the standard for square bore race carburetors. Race-Ready out of the box!

Features and Benefits

• Gold Dichromate finish for corrosion resistance

• Contoured venturri inlet offers balanced airflow for increased horsepower
• Screw in air bleeds for precision tuning capabilities
• Dual 30cc accelerator pumps for additional fuel under initial acceleration
• Dual feed fuel inlets for constant high volume fuel delivery
• 4 corner idle allows you to precisely control your idle system
• Progressive Secondaries for perfect off the line launches
• Stainless steel throttle plates

• Calibrated for gasoline
• 100% wet-flow tested by Holley technicians to assure it arrives ready to run!

Notice - Due to the natural color variations of the dichromate plating process, the plating color may vary from casting to casting (within a carburetor) and from carburetor to carburetor. This is considered normal and is not a cosmetic defect. If you desire a carburetor with no color variation, please shop our black and shiny finish carburetors.
