Default oil cooler mounting - is upside down ok?

I am thinking about duplicating the LeMans oil cooler setup on my series 2.

I found the attached drawing in the special tuning manual, which clearly shows the cooler installed upside down with the feed lines on the bottom. However, conventional wisdom seems to be that mounting a cooler upside down is undesirable for two reasons - trapped air in the cooler and the tendency of the cooler to drain into the sump when the engine isn't running. Is there any truth to these claims?

Also, regarding the sizing of an external cooler - I am looking at the Setrab series 6 - these are about 12" wide. I'm debating a 10 or 13 row cooler. Would a 10 row be adequate for a stock 1725?

Lastly - is an oil thermostat recommended?

Default cooler

We have Harringtons and the coolers have never been a problem. My Ford van has a full tow package which includes an oil cooler the size of a Honda Civic radiator and the hoses are on the bottom. I seriously doubt that you'll encounter a problem with trapped air since the pump is moving the oil and dumping it back into the oil pan. The lubrication setup on these cars are not a sealed system so I doubt that there will be an air lock and with the additives used in even the cheapest oil that meets current specs there are additives to control foaming. The temp range and all the other specs of current spec oil is a world away from what it was when these cars were built.

Made up a set of mounts like the ones in the drawing for my 63 GT. But I located the hoses on the top. Mostly cause it looks better to me and is much easier to get to the fittings to tighten them.

Default cooler

The mounting brackets used by Sunbeam would not permit putting the hoses on top. These photos are of the LeMans that I'm putting together now. This cooler and brackets are the same as the parts on my other two Harringtons with the exception that the mountings of the cooler were moved to the opposite side of cooler so I can mount it lower . They show that it would not be possible to install the hoses on top because there is no space between the cooler and the hinge panel for them. The hoses can be run without obstructing the hood hinges and they go straight across to the opening where the horn would set.

Photos of the brackets and how the fitting touches the hinge panel.

I am about to fashion some brackets for my oil cooler. May I ask what gauge metal you used for our brackets? Did you use galvanized or regular steel?

Any suggestions or cautions for me before I start?

Great photos, thank you very much for posting these! That looks like a 9 row cooler? Hard to tell scale from the photos, is it about 3" tall?

It's the cooler that came in the LeMans but with some mods done to the mounting brackets. I haven't counted the rows.
