Borg Warner 35 Throttle cable. Function and adjustment questions.

[Oldskoolrob]

Hi!
So long story short I have a Holley on my 3.5, and I've made throttle linkages to suit. I now have a new throttle kick-down cable attached to the auto, but I'm curious what needs to be done to attach the throttle end. So, does the cable tell the box to kick down at full extension? What's the best way to set it up (I have to make new brackets and decide how to attach the cable to the carb) as the extension on the cable has less extension than the throttle linkages. If I'm driving at 60mph and floor it, the box should kick down, right?

At rest the cable needs to be set so that there is no slack, but it's not tight such that it's holding the valve open at all inside the box. If I was making a linkage from scratch, first I'd get the measurement between the centre of the clevis pin hole where the cable fits, to the centre of the rod that lever is attached to on a standard car, and then measure the angle that rod moves through between idle and kickdown, that should give you the cable travel, and make your linkage to mimic those measurements as closely as possible. (Or buy the linkage kit that is available for the Holley).

Kickdown happens slightly before full travel on the cable to avoid the possibility of the cable becoming a throttle stop. Once you have a linkage that functions then all the kickdown and shift functions should work correctly if you have worked to the above parameters.

Thanks Harvey, it works out the cable and the throttle (holley) have very similar linear travel so I have dodgy'd something up, that hopefully works as you reccomend.
