George,
If you have a Constant Speed prop you will not see the RPM drop as long
as you are within the authority of the governor.
You will see a change in Manifold pressure and eventually a slight drop
in Airspeed.
Speaking from experience.

If you don't have an engine analyzer (as Peter did), it shows up as a sudden 50 rpm
or so drop -- just like it does when you're doing your runup.

If a man gets into a fight 3,000 miles away from home, he *had* to have
been looking for it.
