Paul,  I bolted a 15" diameter disk to the prop flange just to see how
it would look.  In my opinion it can't get much better.  I think air
coming off of the spinner will dive into the intake duct which will be
a immediately below the spinner.  Notice that there is plenty of room
above the engine  and that the radiator would set inside of a stock
cowl (although I am not using a stock cowl).  Also, I am rebuilding the
exhaust to include the tube with in a tube concept for the first inch
outside of the flange, SS bellows to deal with heat expansion and
relative movement between the engine and muffler. The muffler will set
well off of the side of the rad which will be shielded from it.  The
header pipes will be exactly 16  inches long emptying into a premuffler
that is 7" x 5" x 3" that empties into the 3inch  square muffler
tangentially.  Everything will fit with plenty of room to spare.  Isn't
that an amazing statement.  I had my doubts along the way.  Jerry
