Ok, well...we can make this stuff work.
the vac switch the in the manifold is for the EFE valve, which is that vacuum motor mounted on the bracket that comes off the exhaust manifold.
That vac line would come off of the plugged port on the bottom passenger side of the carburetor, to the switch, and then back to the efe valve
but there is a check valve that needs to go in there. You may want to go back and see if he has any of that stuff.
The orange one is definately for the EGR valve, but I need to peep a couple of diagrams.
But, before all this is done, It would really be great if we could at least do the intake manifold gaskets, that way, we can check it off the list for possible vacuum leaks.

Ahhhh...nahhh. A new intake wouldnt do you enough good to justify the cost, unless you did heads and a cam, and at that point, with the age of the engine, you may as well get an HT383 Crate motor.
