low vacuum.

I have somewhat the same situation. I checked my vacuum the other day and with the car in park and idling at about 700 rpm's I was only gettng around 6-7 in's of vacuum. My cam I purchased was thru Edelbrock I also added 1.5 ratio roller rockers.......the specs are in the attached file

Is the 'norm'.....???......The car runs like a scauled dog.
