Is anyony using a "HOLLEY TRUCK AVENGER" carburetor ??? The ad in JEG'S claims it'll "Maintains idle at45 degree incline" "Designed for low end torque and power" "Improved fuel control over rough terrain". It is rated at 670 cfm. My Q-jet is shot. the auto shop said it's not worth rebuilding and recomends replacing. I've been told a Q-jet is better for off roading. Just wondering if anyone has tried the HOLLEY TRUCK AVENGER. ????????????
