The other shop, the one who I have more experience and tend to trust
more (although they tend to be very by-the-book and high-end) has
_adamantly_ insisted that If I get the plane, she will need a full
engine rebuild. They said that even if she hadn't been static for 10
years, Lycoming insists that all O320's be rebuilt at 2000 hours OR 10
years.

They are being unreasonable. Lycoming *recommends* that all O320's be
rebuilt at 2000 hours OR 10 years. It's not cast in stone for a private
owner. My Lyc. O-360 had 2700 hours SMOH when I had it overhauled; it could
easily have gone more.

Both shops agree about the rest of the necessary work (Avionics, new
struts, new tires, new seatbelts, etc). The only place they disagree
is the engine.

I'm not sure what to think... On one hand I agree, err on the side of
safety. On the other hand, everything I know about engines suggests
that as long as A- there was no opportunity for the introduction of
moisture and B- the engine is fully lubricated/sealed before running,
engine corrosion/wear shouldn't be an issue.

Maybe. I'd still worry about the camshaft. Lyc. cam's are notorious for
rusting from disuse. Why not have it opened up and looked at?
