I replaced a Holley 750 that was a little too much for my car. Installed the Holley Avenger and it made my car run better. Not only that, I installed it and it started right up with little to adjust. I am running a SB Chevy ZZ4.

I have always liked Holley carbs and here is another great choice for street rods. I love the look of the dual feed style Holley and the fact that you can bolt and go with minor tuning makes this one my favorite to date!
