OK Paul, you talked me into it. I figure as long as I'm making a new
engine mount and installing a new rad, I might as well do it right and
get rid of that NACA inlet. Here is the engine mount redrawn to use the
landing gear lower points. The landing gear bolts are already very long,
so I will use cups bolted there that will only increase the length of
the bolts about 1/8". I retained the vertical rect. tubing, just because
neither of the stock hard points above or below the spar is in an ideal
place, and the vertical beam allows me to put the struts down to the
rear shock mount cups at any ideal location.

Also shown is a radiator ducting, turned on in one capture and off in
the other. Rad air exit to be to the airstream just as it is now on my
plane.

You can also eliminate the vert rectangular beams and just go to the top longeron(s?)
with a P51 style side beam. Those rect beams are heavy.

Maybe you can redline it in on this GIF? The upper strut on the right side cannot go any higher, or it will interfere with the exhaust manifold. The CAD drawing is to scale, within +/- 0.1 inch.

OK here it is.
