Throttle Cable swap

[Rusty_S85]

Well lowering the ball on the arm will make the tip in horrible and make the truck undriveable. I would rather save the $1,800 I would spend on this fuel injection setup and just run a carb and fight with that before having a stiff throttle that snaps open resulting in jerking and hard pulling off idle like you are hotrodding it.

As far as the pivot goes, with an aftermarket throttle cable you have adjustment to make it work. What it does is it pulls the pedal up higher by pulling the lever part of the throttle towards the firewall. Making the cable longer with in reason to reach while pulling it closer to the firewall would give you more pull as the pedal is higher up off the floor and as you step on the pedal it is can go down further which provides more pull.

Ive done this before with aftermarket cables on numerous custom installs before and ive raised the pedal as high as it was hitting the built in stop of the pedal.

I know it can be done with aftermarket cables. My problem is an aftermarket cable will not work with the OE bracketry and I could get an aftermarket bracketry that bolts onto the throttle body mount but this would not have the clip part for the cruise control and I do not think the cruise control cable is long enough to move it from the rear part of the intake manifold up to the rear bolts on the carb mount.

But as I said earlier, if I dont use the throttle lever extension it is 1.10" from center of the throttle shaft to the center of the ball mount. I dont know what the center to center is of the upper two holes on the extension which could be added to the 1.10" measurement to give me a center of throttle shaft to center of ball mount measurement. But I do not believe center to center for those two holes would be 0.20" though which would prevent it from exceeding 1.30"

On the E7TZ-9725-A part number, that appears to be the whole throttle pedal assembly. Looking the number up online took me to a FTE post where NumberDummy posted that F2TZ-9725-D replaced part numbers E0TZ-9725-A and E7TZ-9725-A.

Based off that it appears the throttle pedal assemblies were all the same. At least that is how NumberDummy presented it by saying that you couldnt obtain individual repair parts for these but had to buy the whole pedal assembly. The poster that asked the question that he replied with that information to, he didnt provide a year or model or a engine size for application.

In looking at the parts and illustration guide this is what I see

80/ F-U150/350 6 cyl 300 E7TZ-9725-A - Use when floor carpet/mat interference is noted

But I also see this listed and I dont know what r/b means never found that out.

80/ F-U150/350 6&8 cyl All E6TZ-9725-A / r/b E7TZ-9725-A

Makes me wonder if I could possibly have the E7TZ-9725-A pedal assembly.

There were two. E6TZ-A was the standard, and E7TZ-A was used on 300 sixes when there was carpet or mat interference.

Ok, well I have been doing some digging in my guide and I dont know if I am looking at this wrong or not, so I posted my question to NumberDummy as he would know.

As you stated the standard throttle pedal assembly was as follows

80/ F-U150/350 6 & 8 cyl for E6TZ-9725-A

When looking at the throttle cable for my '82 this is what I found.

81/85 F-U100/350 8 cyl 255, 302, 351-2/B 19 3/4" long w/Carb E1TZ-9A758-E

The cable I found for a 4/B for a 351 is as follows

84/85 E-F-U150/250 8 cyl 351-4/B 22 1/2" long E4TZ-9A758-D

Considering the pedal assembly standard was for all 6 and 8 cylinder engines 80 and up and the 81/85 throttle cable for a 2/B setup is listed as fitting 255 through 351 being 19 3/4" long makes me feel that in theory I should be able to bolt E4TZ-9A758-D onto my E6TZ-9725-A pedal assembly which is for all 6 and 8 cylinder trucks and it should function properly.

The question though is the extra 2 3/4" of cable length going to be a problem with a sniper stealth. I mean looking in the paperwork I dont see a specific pedal assembly for a 84/85 E-F-U150/250 with a 351-4/B carb. The only pedal I see that fits that cable application is the 80/ F-U150/350. Problem is there is a star next to E6TZ-9725-A which is the standard part I figured, and below it is a r/b E7TZ-9725-A which is the same number for the 80/ F-U150/350 with a 300 six. Question though I have to ask myself which maybe NumberDummy could answer for me is in 4bbl applications like the 84/85 351 equipped trucks did they use the standard E6TZ-9725-A or did they opt out for the E7TZ-9725-A. Considering that number is listed by itself as being only 300 6 cylinder it makes me wonder if it was an option for any engine outside of a 300 6 cylinder. But if it was a option for any then I dont know why they would create its own listing for the 300 6 cylinder but then throw it as a r/b down the page for all 6 & 8 cylinders. I wish I knew what r/b stood for it might help me understand it better.

But as of now my line of thinking in theory it should work cable to pedal long as the 351 4bbl trucks didnt get the other pedal. I dont think so because if it did then under the 300 6 cylinder it would have listed 351 4/B as well, like when looking up the throttle cable the one I am looking at listed for 4/B is laid out for two seperate applications under the same part number.

84/85 E-F-U150/250 with a 351-4/B

86/67 F250/350 with a 460-4/B.

So to me if that throttle pedal was used on a 351 4/B then it should list it with the 300 6 cylinder.

I understand the whole longer cable doesnt change pedal travel and thus cable pull. But the way I am thinking right now is if the pedal moves enough to move a carburetor from idle to full throttle for a 2/B then it should for a 4/B cause as was stated the pull of the cable doesnt change with the length of the cable. A 4/B carb doesnt have more throttle rotation than a 2/B so the pedal travel should remain the same between the two. Now I do understand the point where the throttle cable mounts will change how much pull is needed, I do not how ever believe that raising the cable mount on the throttle would make a huge enough difference that it would result in the throttle not reaching past 3/4 throttle. That is what many of the people on the sniper owners group I am on with ford trucks are saying, they are saying they get 3/4 throttle at wide open throttle and some of them are not even running the extension lever which tells me there is something bigger going on than pedal geometry. With how big these throttle bodies are, on such a small engine like mine, 3/4 throttle would be well more than wide open throttle if I had a 600cfm 4V installed as these are like 800cfm.

And on the length of the cable, I had to purchase a holley extension for my C6 kick down rod because the 2/B throttle attachments were further back than on a 4/B so I had to buy this 3ish inch long extension to make my kick down long enough to reach the 4/B attachment point. With this in mind if I have to extend the kick down then the throttle cable should have to be extended as well.

If I can use the extension and use a the longer 22 1/2" 351 4/B cable to properly reach I will gladly live with it if the sniper is able to reach more than 75% open at wide open throttle. I can adjust the bolt for the kick down to engage at what ever pedal travel will allow me to reach.

I also found a bunch of used throttle pedals, based off what NumberDummy said in that old post from years ago 80 to 96 were the same pedal but because the number is for a '87 design date I have found numerous 87 - 96 pedals and there are two different styles I see, I found some with part numbers but the part numbers dont match the replacement number that he listed. Wish I knew which one is the one I need to get cause I can pick them up for under $40 used and I have no problem getting one just in case I might need it.

Sorry, I got lost in some of that. But let me see if I can answer some of the questions.

First, it is highly unlikely Bill/Numberdummy is going to respond. He told me on the phone several months ago that he's done with forums.

As for the pedals, the 1980 - 84 trucks didn't come with the E6TZ 9725-A pedal assembly. 1985's might have since Ford did use some parts in the year prior to when they were supposedly "born". But there had to have been an E0TZ 9725-? assembly and the catalog, which is a 1994 version, had that number and any subsequent numbers up to the E6 # removed. But, all trucks of a given year got the same pedal. The one for the 300 six was to fix a problem and was installed only on trucks that came into the dealership with that problem.

On the cable length, while it doesn't change the amount of movement of the inner cable, it can cause problems with routing. Too long of a cable will cause routing problems. In the pic below you can see that the throttle cable is really slightly too long as it goes past the bracket and bends back. But that's the difference the length of cable makes.

And here's the bracket I made. If the Sniper allows you to go across the mounting bolts like the Edelbrock does, with a bit of cutout to clear, you could do the same.

And you want to get the linkage set up like this, meaning with the stud positioned at about the same height as the cable and with essentially no slack at idle. That way all of the movement of the pedal translates to movement of the throttle shaft. In other words, there is no slack.

Going to hazard a guess that r/b might mean "replaced by"...

I hope to get some time to mock up my aftermarket cable to the ProFlo this weekend... Although probably not relevant to your situation.

Yes, "r/b" means "replaced by". The good guys at Ford noted changes that way. The not-so-good guys took the old number out and put the new number in. That's obviously what happened where we have an E6 # showing for 1980 and later trucks. There had to have been an earlier #, but they just wiped it out and put the new one in. And that makes it difficult when one of the older parts shows up NOS as it is hard to tell what it fits.

I have a 1982 MPC and a 1989 version of the MPC on microfiche and a viewer, all courtesy of Bill/Numberdummy and Chris/ctubutis. So if I really wanted to I could go look at the 1982 version and see what the earlier part number was.

Thanks, David. It seems that I do. For sure.

But, with the retirement of Bill/Numberdummy from being our part # guru I'm doing the best I can. I can't replace him, but I can find a few things.
