John,

I figured others would be interested, so I cc'd the list...

It's an Aeroquip unit which I got from Pantera Performance Center. 
However, you can get them almost anywhere. I found a picture of it at 
the website of a local distributor here in Katy, Texas, just outside 
of Houston:

The cooler plus all hoses, AN fittings, oil filter adapter and hose 
clamps, etc. came to just under $600. The braided hoses and fittings 
were as much as the cooler...

The cooler is installed between the lower connection on the pressure 
tank and the lower pipe that comes over the frame rail next to the 
engine. It's the pipe that is bolted to the frame rail.

To make the cooler fit, I had to modify the lower pipe extensively. I 
cut it off about three inches above where it makes a right angle bend 
up. Then I cut out a section near the frame rail so that I could bend 
the pipe forward and then I rewelded it.

The ends of the cooler are then attached to the pressure tank and 
modified pipe with some standard radiator hose and hose clamps.

One hose for the oil comes off of the filter adapter and goes in 
front of the oil pan and up through between the engine and the frame 
just like the coolant pipe does. The other goes around the back of 
the oil pan and comes up over the frame near the starter. I just 
couldn't find enough room to run both hoses around the front of the 
engine.

I did see about a 5-7 psi drop in oil pressure after installing the 
cooler. Cruising on the highway at 80mph showed a 5 degree increase 
in water temperature and about a 20 degree decrease in oil temp.

Hope that answers your questions!

Regards,

Kirby
