No Power Brakes
after installing my new pmd seats, i took my project to the end of the street and back and for some reason I have no power brakes. I do not have a picture of my vaccum routing but i'll try to explain it.
PCV outlet from my Edelbrock 600cfm carb goes to a T fitting. From the T, one goes to my carbon canister, the other goes through my valve cover fitting and on to a PCV valve and my booster. HEI goes to my left vac fitting and my right vac is closed off.
i must have screwed something up. do i always put my booster to manifold vac or something?

Answered your own question.
Booster needs a dedicated intake manifold source. In the case of our car, there is a threaded hole in the rear portion of the carb base, to accomodate a pipe with a union nut.
