Plenty of a vacuum for brakes from a 216, just make sure the master cylinder has a check valve in it.

The GMC 302 I have has a 1/2 pipe tee coming out of the vacuum port, and that was out of a dump truck with a hydrovac. The vacuum port has normal pipe threads on every intake manifold I've looked at.
