    quadrajet for BBC?

     



    I found a big quadrajet 4 barrel carb last night. I tried to id it and all I can find out is it is from/for a '76 Buick. The number is 17056244. It also has a 0496 AFA on it.
    Here's my question. Since it looks bigger than a SBC quadrajet, I was curious what the cfm's were and if it would work out well on my 468.

    It's just my opinion but I would go with a Holley or Demon carb , at least 850 c.f.m. . I always had problems with the Rochester chokes . Especially with a aftermarket intake .

    What 327,JET said covers it for me.Just because it flows 830 cfm does not mean it will wet flow enough gas.
