Holley Truck Avenger
I was wondering if anyone has one of these carbs and had any thoughts about them?

Re: Holley Truck Avenger
I've tried both the 670 and 770 on a stroker bbc. they both were the best out of the box performing carb i've experienced for off road playing. they both were also the worse fuel economy i've experienced as well. -steve
