Manifold.

If it's off of a Q-Jet, it's the big source right in the middle front.

What model?

There should be a large(r) port that is manifold vacuum on the base plate of the carb.

That is your PCV vacuum source. It should not be a small connection like the other ported(timed) or manifold vacuum connections on the carb.

There should be a larger vacuum nipple (3/8") on the rear of that carb for a
PCV hookup.
PCV should be connected to manifold vacuum. :smash:
