Al,
Interesting chart.
Not
certain I am interpreting it correctly, though. Not certain what
the X axis is related to is this the height you mention?
Yes;
it is for a fixed width of 24”. Fixed heat load corresponding to 165 hp
at .5 BSFC. X-axis is height.

It
appears to show that the thicker radiators produce less drag overall than the
thinner radiator. Is this for equivalent core volume or core area? Its my
understanding that for the same cooling core volume the smaller surface face
core will produce the less drag, is this what that is showing or the opposite?
Sorry to be slow today, I'll blame it on leaning over my Aerostars engine bay
for 7 hours yesterday replacing a water pump - aches and a restless nights
sleep.{:>{
By
the way, I order some of those B9EQV spark plugs you mentioned to see if
they reduce the SAG interval compared to the stock plugs.
