Manifold Vacuum Experiment

You can see the point where ported vacuum starts (Door opens) with a single vacuum gauge hooked to the port on your engine in the shop or put your finger over the port and feel it. Don't take my word for it. Often I'm wrong and or intentionally mislead people.

No I believe you. I guess what I'm essentially saying is, it really doesn't matter because I cannot change "THAT". lol

I drove it some more today. Went all the way to the other side of the county to help a friend with an old Mercury with a Flathead in it. Cool car. The truck did much better with the original idle fuel restrictors back in it. Also still, no spark knock and I love how it has more balls at part throttle. Almost feels like something is helping push it down the road. Lastly as @Bewy pointed out, it does tend to run cooler. So I'd have to say this experiment was a success. Since I didn't get as specific with Vixan as I did Gladys, I'm going to revisit this same project with Vixen and see if I have a different outcome than last time. Her cam is MUCH lumpier than Gladys' is and I think she might benefit from this if I do it correctly. We'll see.
