I am trying too but the cable is connected to it and I am not sure how to get it disconnected from the fire wall. I a looking at the manual now.

Do not remove the whole assembly. The cable comes through a white plastic grommet that has a cut in it at the top of the pedal.. You can remove it by taking the return spring off the carb, then reach up above the pedal and just slip the cable off the plastic insert. Pull the plastic insert forward and out of the metal rod. You can then probably bend your pedal back up to normal and install the cable again without spending a dime on parts.

I would just bend the pedal rod back, to gain your cable travel back to normal.
(very common problem) it seems people like to mash Corvette gas pedals frequently !
good luck.



Just pulled the pedal and cable assemblies out. The pedal arm has nice bend in it near where the cable attaches. Before I straighten it was it straight to begin with?

Thanks.

I found that little plastic insert. Pushed it through and removed the cable from the rod. Do not straighten that bend, it is supposed to be there. I bent mine near the pivot point. I gave myself an extra +3/8". I also trimmed the sheathing back about an 1/2 inch from the carb side of the cable because I was bottoming out there as well. Won't know how well it works until I get the engine in the car...

You have a '69 like mine, so yours is like this pic...

Bend the lever on the right (not the solid bent bar) that sticks up in the pic towards you (away from the floorboard). About 1/2" should do it. (I then tack welded mine so it wouldn't bend back again). This will bring your gas pedal about 1/2" higher when all is re-assembled. This angle gives you more adjustment room for full throttle at the carb.

I'm not having any luck getting the picture to pop up.

In the mean time, am I missing a part somewhere? There are two crimped pieces on the pedal end of the cable. Looks like they are the force and closed points of the cable. However, they are about 3/4" apart. Has one of these slipped, or is there a part that should take up this extra clearance as the slotted plastic grommet is only about an eighth inch thick. This 5/8" "slop" is preventing my secondaries from opening completely. I can change things to make it all work, but I'm curious what the original configuration was.

Thanks for the help!

I tried to explain it to you but you don't want to listen. The cable can stretch and the best thing is to go under the dash, pull the cable off, look at the plastic holder in the rod to make sure it's still there, then bend the pedal rod back. It's kind of easy....

No reluctance here to listen.

I've got the assembly out of the car. The plastic "grommet" is intact. I understand that a cable can stretch. My question is what takes up the 5/8" slack in the rear of the cable, as I don't believe that slack is due to stretching.

I have no idea. I have a 69 427 and the new cable I have is a quarter inch shorter than stock. Don't know why and don't really care. My idea is to fix it then dream about it.

I lined up the original 69 cable with the C/C repro and there was a quarter inch diff. I could not get full throttle no matter how I mounted it. See the pic below and how far back the flange on the cable is from the mounting bracket. No idea how a cable could stretch like that but a new one did fix the problem.

This pic.....



The rod part on the right in the pic leading out of view is the part that needs bent forward. It looks like this....

When putting the plastic insert back on/in the cable/arm, had to do it with only one hand and by feel only. Had to file a small V-groove into the insert so I could feel where the grove was and to assist with pushing around the cable. Took a few minutes of fumbling but finally got it in place.
