The double pass radiator increases the efficiency of the radiator by about
50%.
You have tanks on both sides. One side has a partition in the tank with the
inlet at the top and outlet at the bottom.
 The coolant flows across the top half of the core into the non-partitioned
tank then back across the lower half back to the partitioned tank and out
the outlet.

That's the way I went with a custom Ron Davis radiator.
