BRAND NEW HOLLEY 670 CFM OFF-ROAD TRUCK AVENGER CARBURETOR WITH MANUAL CHOKE, VACUUM SECONDARIES, GOLD DICHROMATE FINISH, MODEL # 4150

THE HOLLEY TRUCK AVENGER SERIES CARBURETORS HAVE JUST BEEN TAKEN TO THE NEXT LEVEL. TRUCK AVENGER CARBURETORS ARE KNOWN TO GO OFF-ROADING RIGHT OUT OF THE BOX, SO WHAT COULD BE BETTER THAN A HOLLEY TRUCK AVENGER CARBURETOR? HOW ABOUT ONE IN ALUMINUM? THEY SAVE WEIGHT AND LOOK GREAT. THE ALUMINUM TRUCK AVENGER FEATURES A CHROMATE FINISH TO PROTECT AGAINST THE GRUELING ENVIRONMENTS ENCOUNTERED BY AN OFF-ROAD VEHICLE.

THE ALUMINUM 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 ALUMINUM TRUCK AVENGER CARBURETORS HAVE THE SAME GREAT FEATURES AS THEIR ZINC COUNTERPARTS SUCH AS A QUICK CHANGE VACUUM SECONDARY FOR EASY FINE TUNING; FOUR VACUUM PORTS FOR ALL NECESSARY VACUUM ACCESSORIES; MANUAL CHOKE FOR PRECISE COLD START CONTROL; AND A BUILT-IN FUEL FILTER.
