I just remeasured the end housings on the 3 junkyard engines in
my possession and I thought that you guys might be interested in
the results.  I seem to have misplaced the original measurements
so I got to redo this task.

1.  Rear End Housings (flywheel end) - all 3 housings showed
.0015" to .002".

2.  Center Housings (both front and back sides) - .0015' to
.002", same as the rear housings.

3.  Front end housings - 2 housings showed between .0045' to
.005", the 3rd housing showed .002+" (just a litlle over .002",
just barely perceptible on my dial indicator).
The 3rd housings were the biggest surprise. I expected to lowest
wear here, but actually these showed the most wear by far.  I
thought the front rotor ran cooler?

I also put together a 'mockup' engine out of the worse parts.
This dummy motor has no eccentric shaft or rotors.  I will be
rebuilding my RV-4 firewall forward mockup as soon as I can take
over my wife's half of the garage.  She is a real sweetheart -
she doesn't complain abount not having a garage 8 months out of
the year as long as I make room for her car while frost is
possible.  Needless to say, I just scrape the ice from mine - the
building table for my airplane project takes up my half of the
garage.  You would think that with a garage 22' x 40' that I
could get 2 cars in - well, you guys understand!
