    Holley 4150, 700 DP question

     



    Hi, Is a 5 size jet change, a large change when it comes to jets? My carb came with 69 primary jets, and 78 Secondary jets. I ordered 64's and 72's. Is this a big change?

    It really depends on your engine
    Buying parts I don't need, with money I don't have, to impress people I don't like

    In my experience with Holleys and jet changes, you need to start with a baseline. Then go up or down 2 sizes at a time. Going 5-6 at a time can only make things more confusing .
