I am taking apart this 77 because I need the carburetor. Although I know it is not correct for my truck. I thought it might be a good idea to post the vacuum lines on what appears to be an unmolested truck with the exception of the reman carb. It has the idle stop solenoid. I am the second owner, so I believe it is mostly original. I am posting this to help someone in the future who is trying to get this figured out. I know how hard it is to find the vac diagrams as I am still searching for my 77 302 build. So here it is for future non motor heads as myself. If I am wrong about this, someone please correct this post.

 

That thing is all kinds of molested...

Not in a good way either, like the Jared Fogle kind of molested
