Stock carburetor lay out
Ok so I’m trying to get my car started there’s some hoses that are not connected and I’m looking for pictures or a diagram of the top of the manifold or vacuum diagram to see were everything goes. Also I’m trying to use the quadrajet carb it came with and need to see if it’s the correct one for this car. Please help
What vacuum lines can I plug.
What hoses go here.
Is this the right carb.
I want to go electric choke.
I’m missing something here

Since you didn't specify any details, I'm going to ***-U-ME that the 7040250 carb means that you have a 1970 Olds 350 motor. If your concern is about the two ports at the top rear of the carb, the one with the plugged hose is supposed to be the clean air inlet to the choke stove in the passenger side of the crossover under the carb. I suspect that tube was broken off years ago. The other open port is the vent port for the Transmission Controlled Spark system, which was a prehistoric emissions control system designed to reduce NOx emissions. I don't see the TCS solenoid, so I assume that was trashed years ago as well. I'd be more concerned about the apparently creative hose routing at the thermal vacuum switch at the front of the intake. If you don't have a 1970 Chassis Service Manual, you need to get one.

This is what you're looking for. Purchase an original OEM used paperback edition...new books are often replete with poor copy & difficult to read...buy original, which also contains color wiring diagrams. You may find less expensive, do your research. The CSM is your bible.

The other book you'll find useful is the Fisher Body Manual, which covers all the body components (glass, seats, trunk, upholstery, body wiring, etc). Less of a priority than the CSM, but eventually needed.
The Product Information Manual (aka "Assembly Manual") is a compilation of the engineering drawing used to assemble the car on the assembly line. I'd rank this third in priority but it's extremely useful for a "correct" restoration or even just guidance on reassembly. You'll find that a lot of the drawings in the CSM originally came from drawings in the PIM. When you decide to get a PIM, don't go anywhere other than Paul Sigmund (Hairy Olds on this site). His reprints are light years better than any other you'll find.
