Need Advice! Do I Need a New Camshaft????

I’m actually pretty good with the math!
Easy to add/subtract.
Do you want help or do you want to troll?

Prove your vac advance is adding 4 degrees or it’s from mechanical.
Plug off the vac pot and test again!

Not trying to troll, just pointing it out. When I set the timing to start I revved it to 5500 rpm when checking full timing because I have heard of some HEIs adding a few degrees of advance at redline. It was solid at 32° all the way from 3000 rpm to 5500. I know hooking the vacuum advance up didn't magically add more mechanical advance but I can't "prove it" any other way.

Should I just use JB Weld to limit it to 15° or so vacuum advance? Or with the adjustments not changing the 24° of vacuum advance at idle do I need a new vacuum can anyways?
