How many ports does a Ford 351M vacuum need?
How many ports does a Ford 351M vacuum need?
I found something that says EGR Port vaccum from the carb needs to be run to a ported vacuum switch. When cold, it runs vacuum to the advance. Once it warms up enough, it switches over to the EGR. But, I went and double checked… This system sounds like it needs a three-port VPS, and both on my 351M are two-port.
When was the Ford 400 vacuum connection made?
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.
What kind of vacuum switch does a Ford’78 use?
I drew up a diagram based on everything I had on hand. It uses a blue ported vacuum switch (fully switched at 95°F). It doesn’t have the vacuum circuit for overheating. 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.
Where are the vacuum ports on a Ford 2150?
Aside from the accessory connections stemming from the manifold on the firewall, there are only two things connected on the motor: EGR and vacuum advance. I think maybe I’m using the wrong vacuum ports for their control. Can anyone point me to the correct ports to use for them with the 2150? See if this helps.

When did the Ford 351M V8 come out?
351M production began for the 1975 model year and blocks were cast in the Michigan Casting Center or the Cleveland Foundry. The 351M was the last pushrod V8 block designed by Ford until the introduction of the 7.3-liter “Godzilla” engine for the Super Duty trucks in the model year 2020.
What kind of engine does a Ford 351 Cleveland have?
When the 351 Cleveland was discontinued after the 1974 model year, Ford needed another engine in that size range, since the production of the 351 Windsor was not sufficient. Ford took the 400 engine’s tall-deck block and de-stroked it with a shorter 3.5 in (89 mm) stroke crankshaft to produce a 351 cubic inch (5.8 L) engine.

Is there a 400m engine and a 351M engine?
There are 351M’s and there are 400’s, but no 400M. A little background: Ford didn’t put a letter on their engines, like 351C, unless there was more than one engine with the same cubic inch displacement.
