I checked vacuum again, 19", adjusted the rod up and down a bunch and same feel only with the pedal in a different spot (higher or lower). Rebled all the brakes and same feel as well.
Tested the valve on the booster and thats working properly also and no vacuum leaks on booster hose coming from the engine.
I jacked up the truck in the rear and put it in drive, with the pedal pressed for a normal stop the wheels just slowed (did not stop), pressed harder, same thing, the wheels didnt completely stop until I really pressed very very hard and even then I think if someone had a breaker bar on the lug nuts they could still turn the wheel.
Im going to rip off the booster and drive it down to classic performance and have them swap it for another one to see if that fixes it. Ill let you guys know how it goes unless you have another thing to try first. Thanks again!
