No doubt you are hearing a vacuum leak of some sort.

The line running to the modulator valve on the tranny as well as the distributor vacuum hose and the power brake booster all have "live" vacuum lines. Check them all to be sure nothing got disconnected from the vacuum ports at the carb or intake manifold fittings.

Also check for split/broken rubber or hard plastic lines or the rubber fittings at the ends of the lines, as well as any plugs that might be used to block off unused ports.

It should be an easy fix, just listen and look carefully.
