Product Details

The Holley 0-80555S is a high-performance aluminum spread-bore carburetor designed as a universal replacement for Quadrajet and other spread-bore style carburetors. Featuring a 600 CFM rating and vacuum secondary design, this carburetor delivers smooth, responsive performance across a wide range of vehicles and driving conditions.

Key Features:

  • 600 CFM airflow rating for optimal street performance
  • Spread-bore design with 4.25-inch bolt pattern for direct Q-Jet replacement
  • Vacuum secondaries automatically compensate for vehicle weight, gearing, and transmission type
  • Factory preset electric choke ensures reliable cold-start operation
  • Single fuel inlet simplifies installation and plumbing
  • Universal calibration provides excellent bolt-on performance without extensive tuning
  • Vibratory polished aluminum construction for reduced weight and corrosion resistance
  • 100% wet-flow tested at the factory to ensure ready-to-run performance

The vacuum secondary system allows the secondaries to open progressively based on engine demand, making this carburetor suitable for various vehicle configurations including different rear-end ratios, tire sizes, and transmission types. The polished aluminum finish provides lasting durability and a clean appearance in any engine bay.

I had some concerns at first, however after talking to Joy I am satisfied with final outcome.

Exactly what I ordered in a timely manner. I'd do business again. I have already recommended to a friend.

Good
