Holley Truck Avenger Carburetor 670cfm

Price: $648.99
Item Number: 0-90670
Manufacturer: Holley
Manufacturer Part No: 0-90670
  • 670cfm

    The Holley Truck Avenger carburetor's unique metering block prevents fuel spilling through the boosters at extreme angles, allowing for 40o climbs, 30o side-hill maneuvers, and nose-down descents. This design also helps avoid hesitation, stalling, and the flooding typically associated with carburetors in off-road applications. In addition, high vacuum signal annular boosters offer incredible low to mid-range throttle response.
