I recently bought and fitted a Crane Cams adjustable vacuum advance kit (Part No. CRN-99600-1) to assist with tuning my 350 SBC (Edelbrock Performer Series 600 CFM, 'sensible' road cam and GM HEI distributor).

The installation instructions that came with the adjustable vacuum advance kit state that you should begin with the adjustment wound fully in (i.e. turn the hexagon wrench to the maximum clockwise position).

Question: What instructions don't say (and I can't find anywhere) is whether this position provides MORE or LESS vacuum advance. Anyone used this kit before, or know the answer?

Thanks.
