Restoring 73 Challenger: having issue with Power Brake vacuum and where is proper place to draw adequate vacuum from engine. My first Mopar. Have service manuals for 73 dodges but doesn't show vacuum routing for the power brakes clearly.

Probably straight fro the intake.

there are 2 3/8 ports , the PCV connets to the carb so the waste is distributed evenly to all cylinders & the brakes connect tot eh intake runner usually at the rear of the intake into #7 or 8 runner
