Ok so I don't have a nice drawing program and no pictures yet but let me see if I can "paint" a picture for you.
My rad measures 11.5 X 16 X2" (this is small by current standards isn't it?). It has two hoses at one end(right side); one hose at the other (left side) positioned low on the rad. The right side tubes go to the water pump. The top of the pump casting has been modified to remove the filler cap and add a brass bleed valve. The left side tube is simply routed vertically to become the highest point on the engine with the filler cap and overflow tube there. I don't recall seeing this arrangement with three tubes to the rad and don't understand it.

Plumbing is a combination of aluminum tube (maybe 1.5") and low quality rad hose but it is routed very neatly. Also two runs are within 3" of the exhaust with no baffle in between.

That's cool pardon the pump. No reason why the filler neck cannot be anywhere in the
system. In your case sounds like a two pass rad with the filler neck in the middle
of the rad.  368 cubic inches is on the low side for a rad but as I recall you have 
full dynamic pressure such as it is at 100 MPH. How many gallons an hour did that 
thing burn on the way over? Much depends on the HP you are generating and the 
outside air temp.
