Default 1969 350/350 accelerator cable

Dropping the correct engine back into my 69, there was what I believe to be a Camaro engine in this when purchased. The accelerator cable seems to reach a little bit too far for where the carburetor sits ...

is this fixed by the adjustment close to the gas pedal? I can’t figure how to retract some of this cable to make it fit and operate properly. TIA

I believe your ball for the cable is in the wrong location. It should be in the bottom hole of the plate/lever shown to the left in your photo. Google Corvette C3 Quadra jet throttle cable and page through the images - you’ll see what I mean. There should be a nut on the back of the ball so that you can remove it and relocate it on the carb.

I do see what you mean. Off to the work shop!

The cable is Not installed in the bracket correctly.
The bracket clamps onto the metal section towards the end of the cable sheathing not the cable sheathing.

Found this from the forum - someone else’s photo. Might be the top hole. Anyhow you get the idea.

Excellent - I’d give it a try. Might have to mess with the idle screw at the front of that cam if it was previously set up incorrectly.

That’s what I thought also, but when I look at the AIM it shows and describes the flange butting up against the bracket. Also if I move the cable so that the metal is in the clamp part, it doesn’t seem to reach any of the holes/ball and the cable behind the bracket bunches up along the ignition surround?

if that's a 69, I believe you have the wrong cable bracket

Maybe they had different brackets but everything I have found looks like the one installed. Here’s the illustration from the AIM

In 1970, there were two different cables (Length), one for Quadrajet, different one for Holley. I believe the Holley one was shorter.
Your last picture looks correct to me as well. If you wanted to eliminate the "hump" in the cable, perhaps a Holley version might work.

I can measure my cable length if you like, if you wanted to compare with yours.

It doesn’t bother me as long as it looks and operates correctly, I just didn’t want it to get hung up on the return at all which it doesn’t seem to be. This originally was supposed to have the quadratec and to my knowledge this is the original cable.

The length of the cable doesn't really matter...as long as any curving/humps in it do not cause interference with other parts or become so severe that the cable binds. What matters is 'where' the cable is clamped at each end.

I don't mean to hijack this thread but I am trying to figure out how the throttle cable works, and this thread has some good information. How does the location that the cable is clamped affect its operation? My understanding is that the cable is independent of the black housing. When I move the lever on the carb, the black housing stays in same spot, but cable inside moves. Just as an FYI, my gas pedal has 1" free play and bottoms out prematurely on the floor, so I'm trying to gain a better understanding.
My cable setup looks very similar to @dennis picture above, except I have a lot of cable free play at the carb connection when I push the black piece out of the way.
