    I have two 800 cfm Quadrajets that I built a couple of winters ago. When spring rolled around, I tested them on my 71 GS street car. I kind of forgot about them till a few days ago as I was going through stuff to take to the Nationals for the swap meet.
    For anyone that has a car at the Nats and needs a Q-jet come and see me. I will be in the swap meet area.
    Thanks, John

    As most of you know, I have built 100’s of Qjets.
    To set up these carbs properly, I would need to know cubic inches, compression ratio, cam specs, head work, intake manifold, ignition system, exhaust system, converter, gear ratio, weight of car.
    Thanks

    I am sure this engine will be running 91-93 octane pump gas.
    I will do the 71 carb.
    Be sure to use a 4 hole spacer under the carb, since it will be on a single plane intake. Idle quality and off idle throttle response will be better.
    PM your cell number.
