Default 1967 390 carb question

Hey all, I need to find some pictures or info on my carb it's a 1967 390 4 barrel (FOMOCO c5af f). I'm trying to hook it up to my 59 birds linkage. Does anyone know where I might find some pictures of this?


thx, Dave J

Had these on my 'pooter for another reason but you can see most of the linkage. It's on a stock 1960 / 352 but hoping it will be about the same as the 390?

(the spring bracket is upside down in the second pic - if turned correctly the spring would be straight from front to back - and there is an extra black bracket under the schrader valve in the second pic for cruise control - OK- so mostly stock )

Cool

Looks like someone has some bad and/or missing bell-crank shaft bushings.

Thx gents!
Those help, I had the springs wrong, but I also wanted to see what the link that actually attaches to the carb is like. My 59 bird had a hole in the throttle lever shaft that the throttle linkage goes through (it has a little elbow).
The carb on the 67 390 out of an LTD that I replaced the 352 with has a "ball" type joint. I guess I need to find out if anyone sells a ball type joint for it. Any ideas?

thx, Dave J

Question

The ball on the throttle lever is for an application with a throttle cable. Is the ball swagged to the lever? Can you provide a close-up photo?

Here it is Gary. You can see the end of my T-bird linkage. I just got back from the auto store and they don't have what I need. It almost looks as though I could saw off the ball and use the hole just longer from it. Really don't think that is a good idea though.

Does anyone know where I can buy a throttle cable. I was looking on summit but couldn't find it. I'll bet if I call them they'll know of a part that can convert it.

thx, Dave

Dave,

Unless you want to go with an earlier model carb or change the throttle lever shaft, I would cut the throttle stud off and drill the appropriate size hole to accept the linkage shaft.

Ah yes, I looked at some other pix of the same carb and it appears the hole just left of the ball stud is where the linkage goes on the 59 application. I'll cut off the ball and use that. Here's a pic of mine, and one without the ball.
Is the screw and plate without the spring used for an automatic? Now that I have a 4 speed can I just leave that unhooked to anything? Or should I remove it?

Thx again, Dave J

Oh! One more thing. In this picture, what is the hole with the black arrow? Mine has a little brass tube there. Can you tell me where it goes, if anywhere?
And the one with the red arrow went to a metal tube on the exhaust manifold on the 59 t-bird, but on the 67 LTD 390 it went to a tube and hose that I think was a vacuum line. I thought the red one was heat activated for the choke.

Thx, Dave

If you mean the lever behind the main throttle lever, it is the kick-down linkage for the AT. You can either remove the throttle shaft (not recommended) and remove it or just let it flap.

The threaded inlet on the choke housing is for the suction of heated air from the exhaust manifold (drawn by engine vacuum).

The other (black) is the fresh air inlet for the choke stove. It draws filtered inlet air into the choke stove on the right exhaust manifold and then the heated air is drawn into the choke housing.

Tubing kits are available or you can go full electric choke and block off the vacuum inlet with a brass cap.

I hope I made this clear, if not question again.

I will try and find some good photos and forward them to Ray.

Oh.. Don't feel bad about cutting off the ball stud as screw-in replacements are available if anyone wants to used the carb on a later application.
