    definately new to big blocks but i just traded the vega for a 89 rs camaro w 454. i will assume it is stock so keep that in mind, what would be a good carb for this? it has an edlebrock 600 on it which to me seems too small for a 454

    You can go on holleys web site and look at there Carb calculator. I think a 780 cfm or more would be better.

    Holley 3310 would be a good choice for a stock all the way to fairly hot 454.

    If you like Edelbrocks, a 750 electric choke would be nice on that, I have run that carb on Pontiac 400, Ford 429, and Ford 460, all auto's, with good results.

    You know what I'm going to say. And you know that I'm biased. But being biased doesn't mean that I'm not right.

    Holley is so much easier to tune,cheaper and simple as heck.
    The 3310 would be a great place to start,and under $300.
    They run great right out of the box.

    Q-Jet is always the perfect size. Flows up to 750 CFM which is 5800 RPM @ 100% pumping efficiency,, or over 6000 in real life before 1.5" vacuum is registered at WOT.
