Mike,
The oil pressure is doing just what it should. I would actually expect less
pressure on the outlet of the filter, but different filter inserts have
different levels of restriction.
As for the knock, I would first look to the valve train, they are the major
noisemakers on these old trucks. Check your valve clearance(if not
hydraulic).
