Do you like the tunability Holley's modular carbs, but need to simply replace a Q-jet? The spread bore bolt pattern of the 0-80555C lets you do just that. It has vacuum secondaries and electric choke, so it is useable on a wide variety of vehicles and its single fuel inlet that is in the standard Q-jet location makes it easy to bolt on. Don't trust your performance to just anyone, Holley is the only modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's. ***The 0-80555C is a Model 4175 designed to fit GM spread bore passenger car and light truck applications. It is not compatible with Ford or Chrysler Spread bore applications. The 0-80555C is not recommended for any RV applications. The 0-80555C is not designed to pass any emission laws. The 0-80555C is to be used only for competition/off road vehicles or vehicles not required to comply with any exhaust emissions standards. A carburetor spacer could be required to clear certain components on stock applications such as the Mr. Gasket 3406.
Features:
  • Gold Dichromate finish for corrosion resistance and classic Holley looks
  • Performance replacement for Q-Jet carbs (spread bore bolt pattern)
  • Universal calibration for easy bolt-on performance
  • Factory preset electric choke for easy startups
  • Vacuum secondaries for use on wide variety of vehicles. Compensate for all vehicle weights, gearing & transmissions to allow smooth opening of secondaries.
  • Single feed fuel inlet for easy installation
  • 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.
