I found this board as I was looking for an active Mopar forum. I hope this fits the bill. I need thoughts on what to do.

While this vehicle, I suspect, isn't something you'd usually see on here, but it's the same vintage and sports the lovely pentastar we all know.

I have a '77 B200 van, it originally came with a smogged 318 and a 2bbl Carter BBD carburetor. The previous owner ditched the 2 bbl and intake for a Holley 600 carburetor bolted on a what I found (according to google) to be a 1970 340 4 bbl squarebore intake manifold. The gas went bad from sitting and screwed up the Holley carburetor. I tried to rebuild, but it wasn't working.

I ditched it and decided to slightly downgrade the carburetor to a new Edelbrock 1403 500cfm on the 340 intake.

The problems I now have is how do I hook up the throttle and kickdown linkages? The PO did some hillbilly engineering to make them work on the old Holley. I've got the Edelbrock 1481 mopar throttle adapter and the throttle does work, but it halved the pedal travel so if I floor it, it will only go midway. And I don't see a way to hook up the kickdown linkage unless I enlarge the bottom hole on the #1481 adapter and use a bolt to fasten the kickdown linkage. I don't know if that is the correct thing to do.

Any suggestions? Thanks in advance.

Here are some pics to help give an idea.

You might get away with using this. http://www.ebay.com/itm/Edelbrock-8009-T...1c1&vxp=mtr

Oh my.

Where is the throttle cable?

The rusty piece with the long slot in it right below your throttle shaft should be attached to the kickdown linkage, and eventually to the transmission. There's a stud that should be mounted to the carb it sits over.

The slot is to let the throttle come back to idle if the linkage gets hung up.

I'll see if I can find a picture later, unless someone else beats me to it.

hooziewhatsit, On a Van the throttle linkage rod comes from the front of the engine to the bellcrank instead of the rear.

Ahh, interesting. I guess the engine does sit back farther in a van than a truck Thanks for the info.

This is the set up on my 77 van.
it was converted to a later cable operated deal.
Obviously not stock but it works.
I also have a stock linkage set-up that is supposed to be for a stock 4 bbl in a van. However I have never had it on a motor so I can't say for sure.
It does come from the front like Stumpy says.

Feets and I are very familiar with that linkage. Mine broke off the arm that goes through firewall on my van during the 2004 Power Tour and I had to drive with the dog house off working the throttle by hand at the carb until feets helped me come up with a fix. Got a bit warm inside until we got it repaired. That tour was an interesting trip because my steering box cracked off the frame also. Have you ever tried to find a welder on Sunday?

Here's the linkage I have.
Maybe Stumpy or Feets could identify it.
Also I would recomend a trip to the 71 to 77 Dodge van forum

Lots of good folks and info there as well.

In other applications, where you have your throttle rod hooked up is where a stud would be. On the inside of that stud would be where a throttle CABLE would be hooked up, on the outside of the stud is where the kickdown linkage would be hooked up.

In your case you will have to fab something to work since you are using a rod not a cable for throttle actuation. Either lengthen the throw on the bracket pivot or shorten it at the carb for the throttle. Then ensure that at full throttle (engine off) your kickdown is fully rearward at the trans lever.

I think his biggest problem is the kickdown stud that attaches to the aftermarket linkage adapter. He has no way to hook up the kickdown now. I thought you could buy one of those at the parts store but I can't find a source for him.

Wow. I was lost until I posted this thread. It's somewhat life-saving. Most of my questions/theories were answered!

2004 Power Tour...I saw the convoy, and checked out Christoper Titus' rod. What a beauty.

So I'm missing a few parts for proper operation? Figures.

Supercuda, your pic really helped. It reminded that I think I have the kickdown stud. I saw something like that in the glove box a while ago. Is that supposed to go on the big hole on top of the linkage on the carburetor?

It's raining right now, but I'll provide updates with pics ASAP. Where does the throttle rod is supposed to go now? The only way to hook it up is through that small hole with the cotter pin

I don't think the van ever came with any kind of cable. I'm sure most vans and trucks back then had linkage rods. My old 77 Ford F150 had rods. I think they went to linkage cables in the early '80s for safety.

Boogieart, is that something you would sell to me? Thanks.

Not familiar with van setups, so I dunno. Part of what that adapter does, in other applications not sure about vans, is provide the correct geometry for the throttle and kickdown. The stud should go in the same spot as in the pic I linked. But how it'll play with your setup, again I do not know.

The kickdown stud goes at the bottom of the adapter just about where the linkage rod is now. It should be installed with the pin pointing outward.The top big hole has nothing but the spring attached.

In the attached photo you can see what is needed.

This is the piece that the linkage rides on.
I have several of these if needed.
They are all the same.
It's the piece Stumpy posted about originally.
For aftermarket purposes it is called a "mopar adapter".

This is the bracket I have,
but I am not sure it is a 4 bbl. piece.
That is simply what was told to me when I picked it up.
I hope this will help some.

One part mystery solved. One of the rods were originally on the 2bbl carb, the PO had switched the ends so the hook end went on the carb, the flat side went on the pivot bracket while it was supposed to be the other way. When I flipped it, the edelbrock carb was took up too much real estate to be useful. The original 2bbl Carter BBD is really tiny, looks much like a 1-bbl carb. Time to find some scrap metal...

Found and installed the kickdown stud.

I think the longer and thinner spring is the kickdown spring. It had stretched its usefulness so I'll need a new one.

Is the right spring for the throttle return?

I'm getting there. Did some more tuning on the carb. Smoothed out it a bit, but still not satisfied.
