I'd be interested in any schemes you may have developed for
pre-heating your engine.

One idea I heard was to use flex ducting to direct car exhaust into
the cowling; that does present CO concerns, but on could leave the a/c
doors open. - Mike

Gackkkkkk!, Michael. Build an aluminum plenum around an inexpensive
ceramic electric heater --- you know, the little cube-shaped things about 8
inches wide and 8 inches high and 8 inches deep. These little heaters have
a spark-less blower and are not hot enough to flash gasoline fumes. Round
out the business end of the plenum to fit dryer hose and run the hose into
your cowl. Blanket your cowl to hold in the heat. Go with it until your
oil temp cracks 100 degrees Fahrenheit.
