    for a 454 I would go with atleast an 850 or larger. I have a buick with a 455 stage 1 and it is basically stock I am running a 850 cfm DP. and I think it needs a little more CFM.

    If its anywhere close to stock the 750 will be fine.

    I have an 800 on my 496 and it makes 580 hp and 590 tq.

    Depending on your cam, gears, trans, converter, etc. I'll bet that the money you spend on a Holley will be wasted and there will be NO gain in replacing the Q-Jet.

    Keep the q-jet. For some reason people think that q-jets are bad b/c they are a stock piece. I dont know much about the eddy q-jets, but I am sure it they are the same as the rochester.

    The rochester q-jets are one of the best carbs out there.
