Throttle linkage for 67 single 4v

On my 67, I plan to keep my stock pedal/throttle, but have never been happy with the jenky throttle rod and loose connection to the carb using various clips or cotter pins,


I donít want to go too crazy, and the less ďblingĒ the better, but looking for better options for good solid, bind free connection. Any pics or ideas would be welcome. Iím thinking of sometime along the lines of small heim or ball joint connections that can be easily detached for carb removal.

Carb is a Holley 4150.. 650dp

Almost everything you ever wanted to know about throttle linkage.

IMO, stay away from the commercially available throttle linkages like the SD or Ron Morris. They are expensive for what they are, and most come with substandard rod ends.

Hey guys not to steal the OP question but I did the same, but now my gas pedal bounces around at idle
so it rattles around. I think I am missing a spring under the gas pedal but wanted to see if you folks had
also noticed a higher harmonics or something to the gas pedal with this change?

Finally have all my parts for this conversion. I had to order the fine thread rod from amazon.

I also used some black heat shrink tube to cover the allthread instead of the brake line. I think it looks pretty nice.

How does this set up work the AOD? I have heard a bracket has to be used. Any help?

Glad to hear you got it done! Post a pic so we can see how the shrink tubing worked for you. If you are ever inclined to cut an aluminum sleeve to cover the all-thread, look at Harbor Freight (if you have one locally). They sell a 24" air blow gun for $3.99 that fits perfectly over 3/16" rod. You can't buy tubing that cheap and you're left with a standard length blower after removing the tubing section, making the tubing virtually free! I used it in the linkage shown in my previous post. Just a thought!

I'd have to get a pic when i get home but I used aluminum rod and cut threads into the ends for the heim joints, no sleeve needed.

I'd like to see a photo of your current linkage. Something must be wrong with it, because a 4150 should be a direct fit, and when properly assembled the stock linkage is rock-solid.

I have at least two of those HF air guns laying around the shop. Good idea, if I decide I donít like the look of the black heat shrink.

I'm with 22GT. The factory linkage is incredibly simple, but very direct and smooth. The only 'catch' here would be making sure that it's in the right hole on the carb.

The only other things you'd need to worry about are making sure the spring has enough pull, and that the rod is adjusted to ensure WOT happens when the pedal's all the way down.

Personally, I'm a fan of hooking the spring to the bottom ring of the carb (on the same plate where the linkage hooks up) and then putting the other end of the spring on the 'dogleg' of the factory linkage. Very simple and progressive.

If the bushing on the gas pedal rod is shot, it'll have a little play, but that's easily remedied with a new bushing, and they are cheap.
