How will the FAA determine if a particular homebuilt fits the

(perfectly legal...I can name it whatever I want) with a "Wanttaja
C-85 engine" (looking suspiciously like an O-320 with a new data
plate...again, perfectly legal), and put in the logbook that it stalls
at 39 knots (it's a single-seat airplane....who can contradict me?)
will I be able to fly it without a medical?

Good scenario, and one *I* would be happy to approve. However, part of
the two things I believe you left out are weight and max cruise speed, both
of which I believe you would exceed by a wide margin.
