I've been following this thread with interest and I.m 
getting confused. Sorry if the questions are dumb but 
I'd like to keep these things straight in my head.
	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.
	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 ?
	And finally my two cents worth. How about plumbing 
a single pipe from the block having two ports to the two rads ?
Then having two rads supply two pumps ? Then having pump 
# two feed into the back of a pipe having a check valve or 
whatever ? Then having the pipe continue for  two or three in. 
where the hose from pump one feeds into it at 30 deg. ? and
from there to the block ?  I,m thinking that the smooth blending
of the two hoses would put some back pressure on the check 
valve without causing turbidity or fracture bubbles. 
As I said. Just my two cents.

  "The initial indication is that this may have  caused
 my oil temps to be high.  Water is up to maybe 160F max, so there 
 still seems to be too much radiator, but oil will top 220F if allowed".
