    Q-jet handles hills , off camber , does well in sand , mud , rocks , hell anywhere . They also have small primaries for economy if you can keep a foot out of it , and large secondaries that can be tuned by a spring adjustment to open as the motor needs it for bad boggity boogity boogity power /forums/images/graemlins/thumb.gif

    I tend to lean towards the Q-jet but it really depends on the use. Since your posting here I assume that you are going to be doing some off roading. In stock form a quadrajet is far superior to a stock holley for off road. The holley is easily modified though, and also more easily tuned. A quadrajet is more forgiving of tuning though, and also more able to get an exact tune for all throttle conditions. Also depends on your intake manifold. Depending on your manifold it may dictate your choice unless you want to run an adapter. I personally just think run what you got, two barrels can even be extremely effective off road carbs. Don't go out and buy a new carburetor just because someone tells you its better. But whatever you choose go out and get a book on it so you can understand it better. The best book on quadrajet's is Doug Roe's, and there are a plethora of books about holley carbs. I wouldn't rule out an edelbrock either (though I really don't like them for off road use).

    edelbrock sells both Carters and Quadrajets, there is no Edelbrock carb that I am aware of for our application

    If you doing any wheeling, go with the Qjet. There's a place in California called SMI Carburetor that can custom build you a carburetor. It's based on just about anything you can think of: gearing, tire size, use, altitude, cam profile, etc... They quoted me $320.
