Paul,

    You may already have my radiator cant on file, but if not - mine are
swept back from the nose  by 30 deg.  The rads are 14 1/2" wide including
tanks, 9" tall and 3 3/8" thick.  Like Jim, no analytical planning went into
the angle, it was the smallest angle that would permit the cores to fit
between the Ross drive and the sides of cowling.  I had later thought that
with a slight smaller core, it may have been smarter to cant it just the
opposite direction so that the hot air exiting the radiator would flow along
the side of the cowling instead of back over the engine.  But, since coolant
temp has never been the problem I never tried it.

    Chin location for oil cooler working fine and as weather cools will need
to keep an eye on it to see that it does not get too cool.  I had enlarged
the rear cowl opening also and may need to do something to reduce airflow
thru the cowl during cold weather.  How about a variable intake opening
reducing the dia of the opening as temp goes down {:>).

Good idea to put cowl flaps on there Ed.

We will have some more information on this angled duct stuff
real soon. I am having a professionally made radiator wind tunnel 
made my Sheetcraft in Santa Paula as we speak. The one I made was too
crude :-)
