Raise the mounting point of your throttle cable. Some Mopars have a little 90 degree bracket that will raise it by about 3/4" to 1". You need springs capable of closing the butterflys not barn doors..
After looking at the photos, I would have to agree 100% with the above comment!

I know what you are saying about the angle of the cable. If anything I would probably make a bushing to go under the existing bracket and raise is up. I hate to mess with the stock mounting locations too much, trying to keep it as stock appearing as possible. On the mounting location of the linkage connecting the carbs are you saying to use the large hole above where it is mounted now? If so I don't know that I would have enough pedal travel to get full throttle then, would have to look into it. Here is a better picture of the throttle cable. Didn't have time to mess with it last night, had T-Ball, maybe tonight.

With out having an actually dimension is it hard to tell. The front carb looks like the linkage is way down low. On the back carb the linkage from front to back carb is up high but the cable looks lower.

I did some messing with stuff last night and think I have found the problem. The rod ends on the linkage bewteen the two carbs is very tight. The balls do not move nice and free in the ends at all. Looks like a good system but not very smooth, gives a ratchety feeling when you try and open the carbs slowly. So I either need to find a way to loosen the balls up or just make my own linkage. Oh I also found out what the carbs are, not what I was told originally they were going to be They are 1804 Thunber Series AVS 500cfm .

There is nothing even remotely STOCK APPEARING about the linkage between the 2 carbs. You can buy linkage that will work correctly and look a lot more stock appearing even with those carbs.
On the smaller carbs , the throttle response would be a little more crisp , but not sure how crisp with them opening together on that manifold ?

I know the linkage is no where near stock, but it is what came on it so I just left it. With the shaker step up on top you can't see any of it. If anything I will just make my own linkage so connect them, if I can't get the one in it to loosen up.

They are shoulder bolts, I made them myself on the lathe starting with a piece of 1/4" smooth rod, so I am the cobbler. Originaly yes they did come with an allen bolt, but you can't over tighten a rod end, it's just not possible.
The problem is not the bolts. It is the rod ends themselves. The ball is too tight in the nylon lining of the rod end. It is the way they are manufactured, made by Edelbrock.

I raised up the cable last night just to try. It made no difference having the cable straight in line.

When your running one to one linkage the interconnecting linkages need to be at the same distance from the throttle shafts, not one higher than the other I've used the Eddy carbs and linkage like your suing and if you want one to one lower the linkage mounting hole on the back carb. to macth the front carb. If you want it to be progressive linkage then the back one needs to be higher than the front so the back carb.(primary carb.) can open some before the front carb. starts to open
With this is mind , if he moves the one down in the rear that will change the pull ratio , have the COBBLER in you , , eliminate that hokey 2 piece setup between the 2 carbs , that is more than likely what is causing some of the binding due to the downward angle of the 2 parts.
Keep in mind the 2 ball joints need to be in the same hole on the lever or one carb will open at a different rate than the other and cause binding.

They are both in the same mounting location. Picture might make it look like they are different.

that setup should work if adjusted correctly. i have a repop stock linkage on mine, and it works well, and i like the fact that even though it is far from stock, it still looks more stock than not, if you know what i mean i custom made all my linkage and brackets, as i run a stage V manifold, where the carbs are farther apart, and the bosses on the manifold where the brackets sit don't exist, all the bolts are the same length. there really shouldn't be any issue getting that linkage working, (i had exactly the same thing on my car when i first bought it years ago), but if you want, i'll post pictures of my stuff.

I know it will work and I am 99% sure that the only problem is the tight rod ends in the linkage, they are really hard to turn. I have tried putting a bolt in them and then hooking a drill to the bolt to spin them. Thought maybe they would wear in and loosen up, but not luck with that.

If the balls are riding in plastic you can try boiling them in water for a few minutes then pulling them out and spinning the ball. Maybe you can reform the high spot that seems to be dragging.
I can't afford this.

Those Springs are actually rather wimpy. I don't think I would remove them and operate the peddle. It's a [Edited by Moparts - Family Friendly Site - Keep it clean] when your gas peddle sticks open at high rpm. First I should mention Im using the correct Linkage on the Hemi but the edelbroke one should be fine also. I Had a similar problem the other day with the Hemi Coronet. I had some help from a buddy of mine the other day. Try starting the car, get out of the seat and operate the cable with your hand and see if you have a smooth transition without using the gas peddle. As goofy as it sounds it turned out the neighbor must have mashed the peddle hard as he climbed his fat behind out of the driver seat and bent the arm the comes of the peddle that connects to the cable and it was no longer lined up correctly. Same issue you are having. Like I said my car is an older B Body and I am not sure if the E body is the same but it is exactly what turned out to be my problem. Hope this helps.
