| well. to be a smart ***...you don't want any vacuum pressure. vacuum and pressure are 2 different things.
to answer your question, you are looking to get around 17-20 lbs of vacuum from a manfold source at idle on a freshly built motor. Most of us get anywhere between 13-17 lbs depending on the age of the motor.
