The Off-Road Truck Avenger is designed specifically for off-road applications. The unique fuel metering block eliminates fuel spillover through the boosters at extreme angles allowing for 40 degree climbing, 30 degree side hill maneuvers and nose-down descents to avoid hesitations, stalling and flooding typically associated with carbs in an off-road environment.

The Truck Avenger features a quick change vacuum secondary for easy fine tuning; four vacuum ports for all necessary vacuum accessories; factory preset electric choke for easy start ups; and a built-in fuel filter.

The 670 CFM Off-Road Truck Avenger is the perfect carburetor for small blocks or stock big block engines.

Features:

  • Gold Dichromate finish for extreme off road environments
  • Single feed fuel inlet for ease of installation
  • Optimized off-road calibration that works out-of-the-box
  • Factory preset electric choke for easy startups
  • Vacuum secondaries allow use on a wide variety of vehicles. Quick Change vacuum housing cap allows you to tune for performance or fuel economy (springs included)
  • Compatible with GM, Chrysler, and Ford A/T kickdown linkage. Additional parts may be required.
  • One piece off-road vent tube eliminates fuel spillover during extreme maneuvers
  • Intended for off-road/off-angle use. Unique metering block designed for flood free operation up to 40º while climbing and 30º during side hill maneuvers & “nose down” decents
  • Limited lifetime warranty - Guaranteed to be free from defects in material and workmanship for the life of the product!
  • 100% wet-flow tested by Holley technicians to assure it arrives ready to run!
