        It sounds like Rusty wants to keep his oil temps
below 180 F. I,ve heard that oil temps should be above
212 F so that water, from condensation, will boil out of
the oil during normal ops.

As I've recently learned myself, the accepted maximum oil temp going into the engine is 210 F.  Temps above this point can harm the engine far more than a little moisture. 

        The idea of a two inch pipe was mentioned and
then someone said that the pump is built with a 1-1/4 in.
outlet. Is there an easy way to handle the change of head
pressure and still not get cavatation when changing the
outlet size ?

I believe the pump comes with 1.25" inlet and outlet, but also is supplied with sleeves to fit over the outlet to increase the OD for larger hose sizes.  It doesn't sound like they're worried about the size change.
