Edelbrock 1407 on Cleveland 351 Question

Mesomorphman · 10-03-2009

Hey guys...

I'm putting a 1407 Edelbrock carburetor on my 351 Cleveland. The problem is two-fold... I don't know how to put on the p/n 1493 throttle plate adapter thing. I just don't know where it goes. Also, there is this part that is binding. It is a metal arm that only moves, it seems, when the throttle is opened like past 3/4 of the way. It is attached to the throttle above the cable. However, it seems to be in a little lower position that the stock carb I took off, and therefore binds on the thing that holds the throttle cable sleeve in place (the thing that bolts between the carb and manifold on the backside of the carb). I'll try to post pics later, but this is the best description I can give for now. Thanks guys.

Hello Mesomorphman,
I think i can help. I am a Holley guy but I think I know what is happening.

On your linkage, you have a plate that goes to the back of the carb bolts.
The plate or bracket hold the gas pedal linkage. There is a small boxed area where the cable from the pedal sits in the bracket. Take the bracket off. remove the cable from the bracket. The go to almost any parts store and get this:

It is an easy fix. Costs under $10.00 and will work. You can't use the stock bracket to hold the linkage.
As for the binding, you may be looking at a poart that only opens with vacuum. I would get the bracket, put on the carb and fire her up.

Ah. Thanks Print Dad, but I have that part. I also have this part... Edelbrock Throttle Adapter Plate This is the one I don't know how to use. The part that binds is the transmission kickdown thing that causes the transmission to drop a gear under hard acceleration. It is binding on the thing in the background with the grommet that holds the throttle cable.

Hello, I am attaching a picture that may or may not help.

See part B - that comes out of the stock bracket

part A I am sure you know goes to the point.

I haven't worked on automatics for many many years but I think the kick down
rod is way off. I could be totally wrong but I am pretty certain it should be in area E. Where it is hooked now, I can't see it moving anything.

I could be all wrong but it seems like the kick-down needs to be part of the linkage.
I can't see it working where it is and I am almost certain it is in the wrong place

I would start a new thread and post the great picture. Call the thread Kick-down rod on 197 Mustang. I forget the year

Look for a post by PaulS and send him a PM. I am 100% certain he will know.

You're right, it does attach to the linkage, but if I do, it binds on that thing in the back that holds the throttle cable.

Hello Mesomorphman,
I just a PM to a friend who will have your message.
He is out of Washington and will guide you right.
I won't mention his name but he is real real good.

Just watch and see, he'll get you going..... Print Dad

Mesomorphman · 10-07-2009

Thanks, Print. I appreciate all the help, guys. This forum is a God-send for newbies like me.

PaulS · 10-07-2009

Mesomorphman,
The bracket for your throttle cable needs to be moved so it lines up with the lever. You will need to install the kick-down adapter. I don't know whether Edelbrock makes one but I do know that Lokar makes one. Then your kick down linkage will mount to the adapter and your cable will mount to the carb and lock into the moved cable support.
To adjust the kick-down you will need to first make sure your throttle opens completely by having someone hold the pedal down while you inspect the linkage. Then with the throttle held completely open you adjust the kick-down so it just barely pushes all the way back and down. You can have up to .060" (about 1/16") clearance with wide open throttle but no more than that.

Hello Paul,

First Thanks - I owe you one.

I am thinking Mesomorphman will be confused. He is a newbie and trying to do several things. I too need a little more help..sorry.

I am posting a new picture. I and he understand that the old braket part B must be removed so that cable A can attach correctly. For this I am sure he needs a different linkage bracket. This should be OK and I think he understands this part.

Now the part I and perhaps he am confused on is the connecting of the rod.
I understand he needs another adapter piece of some sort.

But in the end, is he trying to attach to spot #1 or #2 in my picture or is there another place the rod hooks up.

I am pretty certain he will understand about the adjustment of the rod but I am not sure about the actual hook-up. Been over 40 years since I worked with an automatic and I can't remember.

As always I thank you for helping us all out once again. Your gift is appreciated and your advice is invaluable.... Thanks Print Dad

Mesomorphman · 10-08-2009

Haha. Well, Print, you nailed it. I am kinda confused. But I think I get what he is saying. I am not by the car right now, but does spot 2 connect to the kickdown thingy? Is that where the adapter needs to be installed? I already installed this, but am wondering how to install this and whether or not this is what I need to hook up to the kickdown lever properly.

Mesomorphman · 10-08-2009

Or... wait... is that whole bracket B thing removed and the adpater plate installed in its place?

Print Dad · 10-08-2009

Hello Mesomorphman,
See the bracket B in my picture, it goes on the 2 rear bolts that hold the carb.
On a standard transmission, you would take the cable out of the bracket and put it into the bracket I sent you a link to.

because you have the kick-down road, I am not certain if you need one bracket that
holds both the linkage and the rod.

I senb a OM to PaulS for clarification. he will post I am sure.

Just so you know, you can change the throttle bracket, "D" and run the car, it just won't downshift till we get the rod hooked up.

He'll post I am sure... Print Dad

PaulS · 10-08-2009

There is a separate piece that connects to the throttle shaft that connects to the kick-down rod.
It is not directly connected to the throttle lever but it is pushed back by the throttle lever. That is the piece you need to get - a "kick-down lever".
You will also have to relocate the throttle cable so things will clear.

Print Dad · 10-08-2009

First Hello PaulS and thanks.

To Mesomorphman,
I think the part you bought:

Edelbrock 1483 - Edelbrock Throttle Lever Adapters for Performer Carburetors - Overview - SummitRacing.com

might work. Did it come with directions?
I m still a little confused. I think PaulS is saying the part will push the rad back, but I am not sure how the rod stays there unless it attaches to this part you got.

I understand how the rod works I think but not quite certain I understand how the throttle shaft moves it.

I am still trying to figure this ot but I think we are close.
As PaulS mentioned, you need to move the gas pedal cable, but that can be done with the other part I sent you a link for.

Still thinking on this..... Print Dad

Mesomorphman · 10-09-2009

Aaaaaah... I think I got it. I just use the part that PrintDad showed me (which I've ordered) to relocate the throttle cable and then hook the kick-down rod (or whatever it's called) to the thing that the throttle lever assembly doohickey actuates when the throttle is opened to a certain point. I think I got it. I just need to get this part in, now.
