I converted my 318 from a 2bbl to 4bbl, just got the 340 throttle bracket, but it looks like I am going to need a different kickdown rod as the original will no line up with the edelbrock carb.

If anyone has one or know of another solution please let me know. I would like to keep it factory set up and avoid expensive cable setups.
 
There is a extension listed in the thread I posted a link to. At me see if I can find it before I nod off.

This article also shows how to extend the linkage rod to make it fit:

I bought that adapter that seems to lengthen the linkage but I just don't see how that's going to help since it looks like the kickdown linkage is offset too much with the intake manifold that I'm running. I've noticed that the 340 four barrel linkage has a bend to it.

You could replace the thick nut on the throttle/kickdown pin with a thinned nut. The adapter is to lengthen the adjustment. The rear part of the slot needs to rest against the pin and a spring needs to hold the kickdown forward against that pin.
 
I see what you mean and it would make the kickdown lever sit closer but I don't know how much that adapter will extend the lever especially if the post has to be towards the back of the kickdown slot. Wouldn't a 340 kickdown lever go right on without any modification?

Easy to forget that when there is a lot of technical conversation. :poke::lol: but you re figuring out what you need. I can change this to a discussion thread if you want to start fresh with another more specific wanted thread.
