454 Vacuum Diagram

Sorry guys, last post of the morning I promise.

My 454 is a 1984 out of a motorhome. Theres a boat load of vacuum lines and ports all over this dang thing, and its all unplugged. I don't know how it goes back together, the motor came with half of the vacuum lines disconnected. I've been searching, but I cannot locate a diagram that shows where all the lines go. I know some go to the valve for the smog pump, but I don't plan to run the smog pump, so I figured I would just plug the line at that point. As for the rest, I honestly have no clue where the lines go. I need the diagram for the entire vacuum system, including the quadrajet carb, the vacuum advance timing for my distributor, and so on and so forth. If anyone can offer me assistance, that would be awesome. When I have her ready to go I want all the vacuum lines done. I'm dropping it in complete so all I gotta do is fuel, power and exhaust and go. I have the wire harness, I have EVERYTHING. Just need the vacuum. Thanks guys!
