    Anything over about 6 psi will probably case headaches wit a Holley. You don't need more then 5 psi.

    I've always ran vac advance on ported vacuum - passenger side about 3/4 way up on front meetering block. If it seems sluggish on initial take off, try full vacuum on bottom, front passenger side.
