<VV> Plugged hole in side of block

[Clark Hartzel]

The small plugged hole on the RH side is where the oil pressure sender went
on a 1960 engine.
It was moved up top as most of the sender's down on the side of the block
leaked oil.  It probably didn't matter on a 1960 as they all had gas heaters
but later on the heater used air from the bottom of the block and heads to
heat the car and oil leaks were not good!
