Could somebody tell me what carb is supposed to be on a 1969 Chevrolet 1/2 ton 4x4 with a 350? Was there a choice of a two or four barrel?

The standard 8 Cyl. engine was a 307 wth a 2 barrel. The optional 350 had a 4 barrel only.

Thanks Gene, the guy I got the truck from didn't like the automatic choke so he took it out. He removed every part associated with it. It runs great but you really have to pump it until it starts and warms up. Now I need to find another carb to replace it with. What model is it?

Hi Bruce,
I've had a number of '67-'72 trucks over the years. If I remember your truck should have a quadrajet 4bbl. The automatic choke should work off a small choke stove that is screwed to the intake manifold on the right side with a small machine screw. The actual coil has a metal cover that snaps down over the base and has a hole in the top for the rod to come out and go to choke on carb. If your out looking for used carbs make sure to check the throttle shafts, these carbs are known for wearing out the throttle shafts.

You could install a complete Q Jet. from a 1968-1970 car or truck with a 4 Bbbl.....or rob the choke parts from one to make it complete. Avoid the 1971 as it was lean and had the non adjustable idle mix. screws.
The 1968 was also the first year to have the hot air stove (tin) wraped around the right exhaust maniafold with the hot air tube running up to the air cleaner snorkel. This made them run much better in cold weather and eleminated carburetor icing during warm-up.
