Does anyone know if a C-85 fit on the same motor mount as an A-65?

Yes, according to the drawings I have, the A65, A75 and the C75, C85 and
C90-12 all use the same mounts. Upper mounts are 7" apart, lower mounts are
10-1/2" apart and the vertical spacing of the mounts is 11-9/16" for all
these engines. The O-200 uses the same spacing but the mounts are
different. The C90-14, C90-16 and O-200 use Lord bushings in the engine
mount, all the earlier models use the standard conical bushings like the A65
used.
So go for it, Dan. Put that C85 in your Pietenpol and get the best of both
worlds - Corvair like power (better, actually since it doesn't need to turn
so fast and can swing a longer prop) and Continental reliability

They weigh about the same, until the crank snaps on the corvair and you lose
all that dead weight from the prop! ;^)
Okay, cheap shot, I know. I have no clue what each weighs, so please ignore
what I just said.

An A65 weighs 167 lbs. A C85 weighs 182 lbs without starter or generator.
A Corvair weighs somewhere between 210 and 220 lbs and generates 100 -120
hp. However, that horsepower is not as usable as the hp produced at lower
rpm by the Continental.
Lower RPM for the same power implies higher torque and the ability to swing
a larger diameter prop and move a larger column of air. This is exactly why
a Curtiss OX-5 engine which only produced 90 hp could fly something as heavy
as a Curtiss Jenny, weighing over 1900 lbs. I doubt if a Corvair could get
a Jenny off the ground (nor could a C85) where the OX-5, generating its 90
hp at only 1400 rpm could swing a large prop and make very effective use of
its limited horsepower.

Hm. Tempting. Very tempting.
Unfortunately, the remodeling projects we just completed dipped a bit farther into
our checking account than I anticipated.
I'd guesstimate that my A-65 with ~500 hrs SMOH would offset a good portion of
the C-85, though. And I reckon I could keep the McCauley 74-42 prop I have for
the time being...
Yes, it's tempting all right.

Does anyone spin their Piet? Is the general consensus the airframe is strong enough
to do 1 or 2 turn spins, if you don't get drastic with it. When Beech and
Piper came out with the Skipper and Tomahawk, they were originally supposed
to be OK to do spins in them, until a couple of tails fell off.
