Quadrajet Questions

I just bought a caddy carb for my K5, but I didn't know the throttle linkage was different between the 2 carb types, ( I've never messed with a cadillac before ). I could change out the throttle rod, but I was wondering if anybody has ever made an adapter or ran into this problem before? I don't really feel like tearing into this brand new reman carb if I don't have to!

How does the cable connect?

On the ones that use a ballstud, some are removable. Not sure what you've got, but if it won't fit, not sure you have much other choice than to change the throttle shaft.

Might check into the 70's carbed cadillacs, if the car nose isn't too long, the throttle cable might work, as long as the firewall clip is the same. Astro's and trucks used the same clip to pedal relationship, leads me to believe that other GM vehicles probably do too.

You can get different assortments of balls/studs n carb connectors at most decent auto parts stores, or out of summit racing. Or if its a rod with linkage could switch it over to a cable. Lokar makes good stuff. If not use some bailing wire. Ive done it and it works!!!

Well I changed out my throttle shaft and got it installed and running. Now my problem is there are too many ports on it and I only need 2, vac adv and brake booster and I know where they are but what are all the other ones for just to be curious? The locations are, on the back just above the brake booster port 1/4" fitting with vac present, on front base between right idle mixture screw and PCV port (which I have plugged ) 1/4" fitting no vac present and also on front base just left of the left idle mixture screw 1/8" fitting.
The numbers on the carb are 17057230 which is for a 1979 425 ci cadillac motor and I've got it on a 350 bored .060 which is a 364 I think, and a summit cam that is

Should I have to change jets and rods to get it to run right?

Just plug 'em. If its a smogger carb it could be used for all kinds of things, smog pump, flapper valve n exhaust, air cleaner assembly... I think on every carb Ive owned Ive plugged 1 or 2 ports.
