72 360 first start question

here's the comp cam that I'm running I got the valve train idea from a mopar muscle article which compared cam/lifter'pushrod set ups. This one sounded right for me a little more than stock with a good deep sound but a street set up. It's in a 67 A100 van I didn't want it to be a rocket. S i just hook up the vac gauge to any intake vac port while its rinning and that's my total vaccum amount? It's the comp cam magnum 270H
