You need a vacuum gage, hook it to a vacuum port that has constant vacuum. It should have about 19 to 25 inches of vacuum at idle for a stock engine if the timing is set correctly. Now quickly snap the throttle wide open the gage should drop to about 5 then back to where it was. You can also set the timing by adjusting the distributor so you get highest vacuum reading.
