On page 275, Table 12-1, are coordinates for streamline diffusers.  I
plotted this data using Excel and had some questions.  I assume that the
radiator face is to the right parallel to the Y axis.  What do the
different degree values at the bottom of the table mean?  How difficult is
it to turn air prior to entering the diffuser?

I suspect those degree angles are for oblique cooling blocks.
If you check Fig 12-9 on page 273 it refers to alpha.

Main reason I checked Kays & London for their data on the full 
scale test rig on top of the Dodge Caravan. I was surprised
how well the simple 2D wedge works because it conflicts somewhat with the
K&M diffuser data. It also seems to preclude using those K&M duct 
coordinates for modern thin rads under the cowl. Not 
enough room.

BTW Joe were you going to do an FEA on Tracy's motor plate?
If so how did that come out?
