If you really want to run the evaporator core as your oil cooler, why don’t you move the oil filter upstream of the cooler.  That would reduce the pressure to the cooler, and also eliminate some downstream restriction. 
 
I could do that, but not all that easily.  At the moment, the evap core isn't doing the job anyway, so it's probably not worth the effort to try to save it.  
 
The other option to lower the primary pressure is to install an aftermarket regulator on the oil outlet at the front cover.  Bruce said you could also take off the front cover, and modify the original regulator spring to lower the pressure to about 110 psi.  I don't plan to do either of those, but they are options.

Weren't your oil temps way up there?  For some reason, (note to Bill Dube) I was convinced that the stock cooler wasn't going to work well enough, which is why I went with the evap core.  I don't think I've heard John complain about his oil temp (everything else... <G>).  
 
How many people are running stock 2nd or 3rd gen coolers, and have temps under 210?
