what vehicle did GM connect the TV cable to the throttle pedal instead of the induction system? how did that work out? anyone have a part number for that setup and is it still available? if not from GM, does anyone make it in the aftermarket, maybe a linkage company like lokar? last question, anybody have a photo of one that may get me started in the right direction if i have to fab one up myself?
I think I've seen it on a factory TH350 installation...but what was it on? I forget. oh...here you go...early 70s mid size like LeMans https://forums.maxperformanceinc.com/forums/showpost.php?p=2720164&postcount=10 I don't know how you could adapt this to the 700, unfortunately
Scroll down in the cars for sale o my ad for a 32 Ford Chopped Highboy Sedan and look a the chassis pictures. There is a trans picture and you can see the cable and where it goes in my 700R4 trans. Someone like Lokar might have what your looking for?
I was asking about instead of attaching the end to the carb linkage, hooking it to the pedal instead. I know where it connects to the trans
The 700 style transmission is different than the 350 and others. The attachment of the tv cable is critical for the life of the transmission. The distance from the pivot, the angle, and the adjustment of the cable has to be right or the transmission will not last. Go to 700R4p1.html for some details.
I'm cooking ribs right now but when I'm done I'll go downstairs and take a few pictures of the left side of the carb so you can see the linkage setup. I'll E-mail them to you. PM me your address. .
I have over 18 years on the 700R behind the Desoto hemi in my 46 Ford, it survives hooked to an edelbrock 4 bbl with proper linkage with the correct geometry. now I'm considering changing to a 4x2 intake running strombergs, worrying whether i can keep that same geometry with the multi-stromberg set up. I heard about hooking the TV cable to the pedal instead of the carbs, wondering if anyone here might have tried it
do some measuring, see if there's a place on the pedal that has the same travel as the place on the carb where the cable attaches. And see if there's a way to put the cable there, through the firewall. Making sure it's pulling the cable as you push the throttle, of course
Rick; Got some good pictures but I can't post on here. I can just send pictures to your e-mail. If your not interested I understand?
I am currently building a semi off topic vehicle and I plan to fabricate an intermediate bell crank in the throttle mechanism that I will attach the tv cable. The bell crank will replicate the geometry of the throttle part of a carburetor set up for a 700r and using the information in the link I posted
Turbo 400 had a kickdown switch attached to the gas pedal on certain cars. I know that's not what you're asking for, but maybe that's what you heard about?
I'm finding some threads by Google searching "strombergs and 700r4 hamb" Looks like adapting an edelbrook or holly adapter to the shaft on the stromberg might be the way to go but it starts looking very busy on top with the additional cable and cable mount. most of the pics from those hunnert year old threads are gone. And member shifts,, the transmission expert from Wisconsin hasn't been on here in over ten years. I even found a post by me on a thread from 2006 asking about this question, if it could be hooked to the pedal instead and someone had did it but no pics
this is the weiand intake for the desoto hemi, i believe that it will require putting the carbs on spacers to make room for the TV cable to operate. I don't know how much I can raise the carbs without getting into clearance problems with the hood. I want to thank you guys for taking the time to throw out your ideas
Some info here: https://www.stromberg-bulletin.com/stromberg-linkages-with-kickdown-capability-stromberg-97/ Some products here? https://www.limeworkshotrodparts.co...pkkODRipHoa0l_yIk9NbJkvTwjf7sAPmh042me2fg7Ddd
Those brackets are Stromsberg parts designed for a 2 barrel. I've got some good pictures of what's involved to do what he's asking but of course can't post them.
As long as the carbs aren’t a progressive linkage, they usually have a single shaft that operates all of them. That shaft should have a bell crank that is connected to the throttle linkage. Either modify the bell crank to attach the tv cable to or put a stand alone crank on the shaft for the cable. Look at your current cable and see how much travel it uses. Set the link up to use the same travel without putting too sharp a bend in the tv cable to.
I have the Bowler "tru-shift throttle correction" on my c10 truck with a 700r4, it was a little spendy but ive also grenaded alot of transmissions over the years for various reasons so it was justifiable. Works well and setting it up was easy, just ratchet the throttle a couple times and it adjusts itself. I just checked and they are even more proud of it now price wise, but sometimes its nice to not have to reinvent the wheel for everything and just get something that goes in without alot of headache and does what it says its going to do.
If you can get a throttle pedal attachment to match exactly what happens with a standard setup, you should be good. The diagram attached by @Algoma56 is what you need to replicate. It will take a lot of pissing around, but it is doable. I would be looking at doing it off the carby linkage. I think it would be easier.....
@silent rick , can you post the photos from @krylon32 ? I'm interested to see how the throttle pedal works as TV cable actuator. Thanks,
gary's photos were just how to attach the cable to a 4bbl edelbrock, basically the same setup i've been running the past 18 years. the body on my 46 has been channeled over the frame. the edelbrock carb i'm running has been adapted to the desoto's 2 bbl intake and has a caddy/olds air cleaner over it, all of that resulting in the air cleaner having maybe a half inch of clearance under the hood. as you can see by the photo of the weiand 4x2 intake i posted above, the throttle shafts are very close to the intake, in order for the linkage for the TV cable to work, i'd have to run spacers under the carbs. from very quick, half hazard measurements, the four deuce setup barely fits under the hood now, if i have to use spacers in order to get the cable to work with the correct geometry, it probably won't. that is why i was looking for an alternative way to connect the TV cable and i remember reading about hooking it to the throttle pedal here on the hamb
The typical setup has the TV cable fully extended, when the throttle is wide open. How far does the cable travel from idle to wide open throttle on a carb with the correct linkage geometry? Your current setup should provide that dimension. It seems that the cable would have to travel that same distance from idle to wide open throttle when connected somehow to the "gas" pedal or pedal linkage. Someone above said that in less detail, and I think I would agree.
If you go to a manual valve body you don’t need a TV cable. But, you will need to select and shift the gears manually.
Back to your photo, what is the distance from the throttle blade shaft and the intake runner on the carb with the greatest distance?
Probably not much help, but here is a photo of the linkage on my quadrajet with no geometry corrector needed. The TV connector is behind the spring. The throttle blade shaft is just below the stamped A. Let me know what dimensions might be helpful.
