I did manage to find a vacuum diagram for the 400 dated for June 78, which was about a month before my car was built (as well as a couple 351M diagrams dated well after my car was built). But it includes a three-port PVS along with a pair of two-port switches. So, I’m not really sure it applies to its cousin.

All I know is that I want no part of any vehicle built between19 71 and 1990. They didn’t even run good back then. It all had to do with emissions during the initial engine warmup. Shift points were altered a bit and ignition timing retarded for the first few minutes of operation. This type of thing was common back in the day.

I learned that requires a red ported vacuum switch (open at 235°F) with three ports to switch between ported vacuum and manifold vacuum. My engine doesn’t have one.
