Guys:
I am ready to pull my hair out. I wasted most of a day attempting to assemble a workable throttle pressure linkage from the parts I have and I think I am going backwards.
This is a 1973 Dart Sport with a 318, A904 w/ console shift. 1968-9 340 intake with an Edelbrock 600 carb.
I understand how it works, so that's not a problem. I have the Mopar factory manual, so that's not a problem either.
What IS a problem is that I can't identify the parts I am using. I've posted some pictures here to help illustrate what's going on, so let's look at those:
In the first picture, you see the throttle bracket of unknown origin. It clearly isn't the correct 4bbl bracket.
In the second picture, you see the same thing except a wider view which shows the the upper rod in it's correct closed throttle position. However, notice how vertical the pivot point for the mid-rod is. The throttle pivot at the bracket is being pulled too far forward.
All the upper rods I have are the same exact length and none are adjustable.
In the third picture, you see the bottom pivot with the trans arm pushed all the way rearward(WOT). Here again is another conflict: The lower pivot is too far rearward and the mid-rod would never attach in that position and in fact never allows the trans arm to move that far back.
I am 99 percent sure that is the adjustable lower rod that I just removed off a '74 Valiant a few months back, and I thought it would be at least usable here.
In the last picture is the last mystery:
On the left, you see a bottom pivot that is narrow, and uses a bottom rod that is not adjustable. It goes in the trans arm and is retained by one of those clips that goes along the rod itself, not a cotter key.
On the right, you see the wider version, which is identical to what's on the car now.
So, hopefully all this junk can be identified and I can understand what I have, what will work, what won't. I've searched till my head spins and it seems like everyone has some different setup.
I'm all for buying a correct 4bbl throttle bracket. Somebody said Mancini sells them but I couldn't find it. Any concrete info about "You have a '73 4-bbl smallblock A904 car and you have to use THIS bracket, THIS midrod, THIS lower pivot and THIS bottom rod" would be greatly appreciated:supz:
Thanks.
