REFLECTOR:Cooling one cylinder

I made my bottom of cylinder shrouds to provide about 1.5" of opening
between the shrouds at the bottom of the cylinders.  This looked awfully
small to me but I got this measurement from a Sundowner in our hanger that
has a O-360 180 horse engine in it.

My heads are running GREAT.  405 degrees max after a 3000' climb with the
plane fully loaded.  My cruise CHT's are around 330-370 (rich to lean).  But
I also have the downdraft NACA inlets.  I did not have to fill up all of the
cracks between the upper plenum and the crankcase.  I am really pleased with
my cooling system, oil runs 180-210 degrees and cabin heat too with a single
oil cooler.

Another benefit of the Reflector - I have collected everybody's good ideas
and have come up with a really nice running Velocity!!!

THANKS EVERYBODY!!!!
Good luck Scott,
