My new Edelbrock carb…

Before installing the new carb, I need to determine if the old

"distributor vacuum port is TIMED (no vacuum at idle) or FULL (vacuum present at idle).

Apparently, I could have tested this when the car was running, but that was years ago. Can anybody tell me if I have TIMED or FULL vacuum?

69 Dodge Polara, with a 383, auto trans, cruise control, power brakes and steering. It was stock with a 2 barrel carb, but the new one is a 4 barrel. Hope that helps.
