    That part is supposed to fit all 4150 carbs. Looks like it would work:



    Is this where you're talking about bending the link bar at?

    I agree. You can always cut the threaded rod if it's too long.

    Yes, it's actually designed to be bent (adjusted) there.

    Bought Holley part #20-122 and adjusted it with the throttle body on the engine. I achieved what I believe is a perfect 1:1. I had to adjust the linkage to get the secondaries just off bottom (equivalent to 1/4 on the linkage). I'm going to fire it up tomorrow, and see how everything responds. Prior to this my idle speed screw and IAC were all in order, but I might have to readjust. Seemed to fix the throttle hitch: http://forums.holley.com/showthread....Throttle-Hitch

    Yes, that part can be installed with the throttle body on the engine.
    LOL! You've been so adamant about not removing the throttle body.

    I achieved what I believe is a perfect 1:1.
    FYI: Be careful with this. If it's exactly 1:1, any little idle speed screw adjustment will also open the secondaries the same amount.

    I'm disappointed that you posted that video, without showing the new secondary link in action.

    So, do you want a little bit of drag on the secondaries?

    I would delay the secondary opening just a little bit, to account for slight thermal/mechanical variances.
    Be sure to also check the linkage at full throttle (ensure it doesn't reach full throttle too soon & bind).

    I adjusted back out 1/4-1/2 turn, so the primaries still have a little head start over the secondaries. WOT has no binding, and the the blades are equally open too.

    Ha ha, I will delete that video and shoot it again.

    Yeah, it looks really nice...so I'd like to see it in action.

    Good video. That throttle linkage activation looks good to me. Thanks for the update.
