Has anyone ever run a dual quad set up and figured out how to use the auto transmission kick down. My current set up is dual holley 465's mounted backwards. I have never seen anyone make a linkage set-up that would accommodate this. If not, why has no one figured this out? It seems like a good way to create a unique item and make money.

At least make fun of me or something.
O.K. :p! That is something I gotta figure out too. Heck, I haven't even figured out my throttle linkage yet! Gotta make a bracket as I want to stay with my factory cable throttle. All the 2x4 stuff came on cars with a 4 speed and the old style mechanical throttle.
O.K. All you Rube Goldberg guys help us out!

Just use a Lokar cable and set it up so that at full throttle you are pulling full on the cable.

What do you have for carb linkage? I guess you are pushing the throttle linkage rather than pulliing since they are mounted backwards?

Normally the cable is hooked up on the bottom side of the carb linkage so that as the linkage rotates, the bottom of the linkage moves to the front of the engine. In your case, with the carbs mounted backwards, the top of the linkage moves toward the front of the engine, so hooking up the cable up there would work.

Carb linkage works as normal just a different location front to back. I am gonna fab up a bracket that mounts using the back carb bolts. I need a place to mount my cable. Does the Locar kick down look like it would work on the 2x4 linkage in the first pic?

Sorry guys, was away for a while. My linkage is the Carl’s ford parts original 427 type linkage (bell crank type). I was told this was the best quality for that type of linkage. The carbs and fuel log came from Price Motor Sport Engineering. The cars came with trunions pre-installed. I am guessing that ford never made a provision for anyone wanting to use this with an automatic transmission. I have nothing against Lokar or cable operated linkage, as I had it on my 53' Ford. The only problem was I could never get it exactly right. It was close, but always just a little off. Thank you guys again for all your help.

Ok, is there any down side or harmful effect to running a vehicle without its kickdown?

Also depends on transmission. I have run a C6 without the kickdown rod hooked up for a couple of thousand miles before I found that I hadnt hooked it up. Boneheaded I know but It didnt hurt the transmission at all just didnt want to down shift at WOT. Not sayin it wont hurt it, just my experience.:)

On a C6 the lack of a kickdown won't hurt anything.

Using the normal dual quad throttle linkage and a kickdown can be a challenge. We made one up for a customer car, but needed to have the vehicle on site. If I recall we fabricated a bellcrank arrangement at the firewall end.

So Barry R, that would not be something you could mass produce and sell? I have all the fabrication ability of a cinder block.

Once you get everything set-up, you may find you don't want the kick-down. After downshifting, losing traction, and getting sideways, all unexpected, you may want the control weather or not to downshift.

Just from personal experience. :D

BTW, I ran a C6 tens of thousands of miles without the kick-down with no problems.

Thats a good point. I didnt think of that. DJOHAGIN, How much HP/TQ in an engine do you think it would take to produce a situation like you mentioned. (assuming highway gears and a very heavy car?)

Mechanical linkage? Didnt some cars have a rod extending down at the same point that it goes up for the throttle linkage that has a cable to the kickdown lever?

Like this


Cable goes from the one rod to the kickdown, carbs dont affect it.
