I didn't let it run very long.  30 seconds max.  This was after oiling the
motor with an air gun on the oil pump shaft.

After ripping everything apart and putting it back together yesterday I got
a call from the engine builder.  We had spoken to them earlier that my
Father and I thought that there seemed to be something wrong with the
length of the oil pump shaft or something related to it.  It seemed to us
that the oil pump was not being driven by the vacuum pump.  There was some
small damage around the slot in the bottom of the vacuum pump where it
drives the oil pump.  The builder dismissed this as crazy talk as he was
looking at engines in their shop and couldn't find a problem...  Until
yesterday afternoon when they figured out that there was a problem with
some of the vacuum pumps they had on hand.  Supposedly the bottom of the
pump housing where is seats to the block is incompletely machined not
allowing the vacuum pump to seat all the way down!  They are going to
machine the pumps they have on hand but I am going to try to mod the pump I
have here just to get this project finished.  I just wished they had found
this problem before I spent an entire day trying in vain to figure this out.

Hopefully I can grind a little off of the pump and get this van driving.
Wish me luck.
