Working on my 70 k5 with 350 in it ,put a 72 4bbl intake and quadrajet on it. These were off a parts 72 auto I have but the 70 is a three on the tree, anbody got a close up of the throttle linkage on the side of tje quadrajet? I cant find a pic in my service manual or do i need an overhaul manual?

I'm not sure this will help, Brian. The picture is of my 69 2wd, with a TH400 and 350. I know, at minimum, you need to ignore the downshift switch and bracket to actuate the switch.

If nothing else it'll take your post back to the top.

First is a pic of a rod and not a cable it would look the same pretty much.

Here's mine just doesn't have the cable connected.

You have a clearer picture (lighter) and do you have one at the accelerator pedal as well? What year is your truck Tree 50?

Is it safe to assume your 70 still has a rod from the firewall to the carb? The change to cable was made in 71.

Yes, i pulled it off a 69 i have for parts, but the 69 is an automatic and a 2bbl but i did use the rod.

I can get one but it looks similar to this pic (not mine) I had to bend the rod on my 68 cause it's curved if you go straight up.

Mine is a 68, pulled throttle cable and whole pedal assembly from a 77.

Does your carb linkage look like Tree-50's? If so, maybe you could take a dremel or die grinder and remove the stud that holds the cable on a 72? Then drill it out if nec. for your rod style linkage.

Otherwise, put on the cable. You can get a carb adaptor at the u-pull-it off another quadrajet that has a cable, if you didn't get the one off the 72. That also opens the door for a down-shift cable if you decide to go automatic in the future.

It's a better way to go if your motor mounts break, there is less chance of the throttle getting stuck.
