Well that was a fun weekend.  Got the garage all cleaned up, the workbench
rebuilt, got the 1147 onto an engine stand (after pulling the rear plate)
and even dug into the engine.  It was running previous to its removal from
the car but was smoking so badly the military wanted it for doing smoke
screens during wartime.

I'm amazed that it held together.  My experience in engines are Chevy V-8's
and the 2300 L4 OHC Vega engine.  This thing is down right *tiny*.  And
none of the bolts were on tight at all.  Even the cylinder head nuts on the
studs.  Four required a breaker bar and they were only on at 60 lbs.
Everything else needed only a standard socket wrench and very little effort.  

No compression to speak of in the engine when I started digging in.  Found
out that #3 and #4 suffered piston damage and the top edge on both had
large missing chunks providing you with a nice view of the rings.  Strange
that there was no damage to the cylinder walls though.  No marring, no
scoring, nothing.  They look great.  Actually other than being greasy, the
entire engine is in good condition.  I was worried about boring it out and
going full tilt on it, but it looks like this will be an easier job than
anticipated.  Have to replace all four pistons and do the standard
rings/bearings job, but it looks like this engine will work.

Piston set prices seem to be all over the board between suppliers.
Suggestions for whom to work with and whom to avoid for internal engine
components?
