One added nice thing about the Q-Jets (and why they worked so well for a "corporate" carb is they are a spread boar so you usually are running on the smaller primamry venturi, and then under WOT you hit the BIG secondaries!

So better gas mileage and better performance all in one nice package. I know my Holley sucks more gas than my Edelbrock did... and I assume the Q-Jet would be better yet (if I could keep my foot out of it)

But yes, get one you are either familiar with or some one you know is... or feel comfortable with
I hear the Demon carbs (Holley design) are an improvement and easier to work on etc...
