Demon Carb Kickdown?
Thought I would post this here as well.
I recently bought a Barry Grant Speed Demon 750cfm carb with the ford kickdown linkage. I am installing it on my 79 F-150 with an auto trans. Does anyone have any suggestions or pics of how the stock kickdown rod will hook up to the Demon. Any way I have tried still ends up with the kickdown rod interfering with the throttle linkage. The rod end is too large and it binds. I can probably grind down some excess and maybe make it fit, But I decided to appeal to you guys in search of a better solution. Thanks in advance for any help.

aint sure
I had a bud over the other night and he says his demon kickdown linkage is different than mine. I ground the end of the kickdown rod and got it working. Now there is no place on the kickdown to hook the return spring that does not interfere with the throttle linkage. It looks different than any ford kickdown I have ever seen but according to the numbers it is the correct carb. I dunno...WTF. I am going to have to hook the return spring to the actual rod in order to get it working. To me that just aint right. I think Barry Grant and his boys should do some more homework.

tranny spring
Is there a way to tighten that spring? Mine comes up just not quite as far as I am thinking it should. Once it returns you can still pull it up a ways. I also was wondering if it did not have enough spring pressure if it could accidently kickdown, say on a bump or washboard roads.

The valve inside the transmission that it actuates is spring loaded, so it will push it out as far as it needs to to keep it disengaged.
You could also fab a spring down on the transmission lever to the case, perhaps if you feel the need to.
