Technical Edelbrock Throttle Linkage Issues

Discussion in 'Traditional Hot Rods' started by Musclecarsornocars, Nov 4, 2018.

  1. Hey guys! So I’ve recently decided to swap over from a 2 barrel Rochester 2CV to a 4bbl Edelbrock performer 500cfm carb in my 64 impala 283. I’m also using a 62’ 283 4bbl manifold that I picked up. One of the issues I’ve ran into was the my stock throttle linkage just wouldn’t fit/line up with the carb. I’ll include some pictures and you can see because the carb is wider than the 2CV, the linkage is skewed on and angle and just will not fit. It’s also not long enough it seems. If you guys know of any solutions that would be great! Also would like to keep it as original as possible, so minimal cutting, drilling etc is preferred! Thanks![​IMG][​IMG][​IMG][​IMG]

    Take some of the bend out of the linkage rod.

    Maybe check to see if they make an adapter. I know when I use an Edelbrock on a Mopar they have an adapter arm so that the linkage will line up. Worst case, you might have to go aftermarket like Lokar or something to make it work.
     
  4. Earlier today I was searching around to try and find something but I’ve only come across different cable adapters. I wouldn’t mind an aftermarket setup, as long as I don’t need to do too much hacking if you get what I mean. I’ll have to look into Lokar.

    Unbolt the throttle arm [by the firewall] and "Z" bend it over to the LH side.
    It isn't that difficult in a Vice.

    If you don't want to touch that, look for a shift rod off a Hurst Shifter

    Straighten the rod out, run a die over it to get more threads, cut it off as needed. Simple, and over and done.

    That would be a die not a tap.
    I have a few different factory straight ones, some are fine thread, some are extra fine.

    . First you need an engineering plan. The after its approval a work order will be requested. The work order will then be place in the correct order for dispatch to assign a technician to complete.
    Steps to complete throttle arm revision.
    1: Remove throttle arm from foot feed on firewall retaining all attaching parts
    2: Place arm in 6" vice centering the angle equidistant in the vice from each end of the angle.
    3: Turn handle on vice until tight removing bend in throttle arm.
    4: Repeat above instructions on second bend.
    5: Reinstall on vehicle connecting carburator throttle arm to foot feed using the original removed attachments.
    6: Adjust throttle rod length using the threaded adjuster.
    7: Insure full throttle is achieved but having assistant apply foot feed from inside the vehicle.
    8: Return the work order to the dispatcher.
     
  9. Bending the rod might fix the throttle linkage, but the other problem is the kickdown linkage. I can get it to fit, but it’s way too short. When it’s installed, you can’t even open the throttle.

    Perhaps you should be on a Musclecar Forum instead of here. Here we have learned how to adapt things mechanical to make them work. Working on hot rods almost nothing falls into place, most everything has to be modified. You have 2 of the simplest things to adapt and modify. Get to work you can do it!! Ralphie

    Did you unscrew the carburetor end of the linkage to see just how far off you are? It looks to me like there are plenty of threads left on the throttle rod.
    On the transmission linkage:
    1. Stick a rag in that open distributor hole on the intake
    2. Remove the kickdown linkage from the car
    3. Cut it in half
    4. Weld in an inch of 1/4" rod to lengthen it
    5. Dress up the welds
    6. Reinstall it.

    I'd heat the linkage up at the offset parts and straighten them out a little bit. Can probably do it on the car if your careful. It won't take much and you gain length as you make the offset smaller, plus you can align the connector at the carb while doing it. The kick down rod is simply too short. You can try heating the very top of the part sticking up behind the motor and rotate it forward a bit. It doesn't look like you need much. If that can't be done take a piece of 1/8" flat stock about 1" long. Drill 2 holes in it. Bolt that to the top of the arm through one hole and then put the pivot stud the linkage attaches to in the other hole. Use good lock washers! Should gain you enough to allow it to connect.

    First thing I would do is stuff a rag in the dist. hole. D

    Even the muscle cars have to be fabricated. I have yet to pull a performance part out of a box and just "bolt it on". Without the aide of a vice, welder, and a grinder... Nothing fits! I swear to God!!! LOL

    Hooking up throttle linkage is about as basic a modification there is. You really didn't think it would be a bolt up after the manifold and carburetor replacemant did you? Nothing is easy, bolt on parts that are supposed to fit rarely do. Hot rodding requires ingenuity, mechanical aptitude and some manual dexterity. There's lots of ways to resolve your problem. Good luck on figuring it out.

    Get a piece of all thread from hardware store with the correct thread pitch. Where are you>
     
  19. Think I’m going to try and bend the existing throttle linkage to fit like a few of the guys here said. As for the kickdown I think I’m either going to cut it and weld a piece in to make it longer or look for a longer rod. Thanks for all the ideas guys, it’s much appreciated

  20. Might give that a go after work today. In the New York area

    Found them.
    20181105_091359.jpg


    These are all 1/4-32 which is extra fine (common GM) thread, not standard 1/4-24 threads.
    Don't even know what that one is with the angled ends.
    Only have one end pivot.
    For the most part, my interest has always been the 64-67 Chevys but not exactly sure what these are from, just left overs.
    I don't want to give them all away but if you can use one just reimburse me the cost to mail from Oregon to New York.
    PM me your choice and your address.

    With a vice he can make his look exactly the same as the ones above.

    PS: I agree with putting a rag in the distributor hole. I guarentee the cotter pin with be in there just as soon as he removes it.

    Can the rod be inserted from the other side of pedal arm to reposition, before adjustment bending?
     
  25. Don’t worry guys, I did cover the dist. hole. I just set the intake in place and quickly mocked up the carb when I realized the linkage issues and took the pics

    CAN the rod be re-positioned by entering the arm from the other side??? Will the cotter key work on the opposite side???:p:eek::oops::D

    Some guys shouldn't be confronted by situations like "the Bends". They would be subjects for decompression.:confused:

    Them 'Vices' ain't vises, BTW...:cool:

    You could make one from 2 x heim joints and a piece of threaded rod .

    Or if you're the "king of cheap" [like me] go to the local "U-Pull" and vulture a long Gas strut of a Van door.

    These have nice chromed rods, with "clip-on" style ball joints.
    Cut it apart to get the rod out ,and shorten and rethread the other end to the desired length.
    Then screw on the other ball joint

  29. Unfortunately I couldn’t really do much today. The car is outside and has been raining hard the whole day. Hopefully if the weather holds up tomorrow I’ll be able to get a better look at things.
