Product Details

The Edelbrock AVS2 500 CFM Carburetor #1903 features advanced Annular Flow Booster technology specifically calibrated for dual-quad applications running two four-barrel carburetors. This innovative design delivers exceptional fuel atomization with near EFI-like drivability and throttle response that you'll notice immediately.

Key Features:

  • Annular Flow Boosters with eight equally spaced orifices provide superior fuel atomization compared to traditional down-leg boosters
  • Electric choke for convenient cold-start operation
  • 500 CFM airflow rating optimized for dual-carburetor setups
  • No power valves to blow out during engine backfires
  • Tool-free metering rod and spring changes for quick part-throttle tuning without fuel draining
  • Qwik-Tune Secondary Air Valve allows limitless calibration adjustments with simple hand tools
  • Two-piece design enables float level adjustments and component replacement without removing carburetor from engine
  • Updated booster clusters calibrated for modern fuel formulations and octane levels
  • Available in satin finish

The AVS2 design eliminates flat spots and dramatically improves throttle response in the low- to mid-RPM range while maintaining excellent top-end power. This carburetor holds its tune exceptionally well, keeping your adjustments consistent for reliable performance. Designed, manufactured, assembled, and calibrated by Edelbrock in the USA.

Good service

Easy to find correct part and order

It was easy

I'm very happy with shipping time and receiving time. I ordered the wrong part. I wanted step bars and I order the wrong part. So how can I send the wrong parts back and order the step boards properly?

Quick and easy
