I have reviewed Dennis Savarese's power chart and am still getting the feel for
the engine.
Just how much oversquare can you run these things.
It just doesn't feel comfortable running 1800 RPM at high power settings. Is this
a legitamate concern or just my prejudice from running direct drive opposed
engines?

Nothing to be concerned about. Take a look at the original Russian power
setting chart and it clearly suggests the engine being run "over square".

The only restrictions that I know of are the 5 minute limit on full power.
Radial engines are often run "over square".
The basic design allows this as they do not have the same torsionial
stresses on their single throw crank shaft. Multiple throw crankshafts set
up torsional and bending stresses on the long crankshafts on other designs.
The simple single plane cylinder arrangement also sets up different
vibration patterns that are easily counteracted with floating
counterweights. The M14P has primary vibrations in the 4.5 th order and the
ninth order that are way different from the four and six cylinder opposed
designs. The M14P has floating counterweights that effectively dampen the
vibrations.
As Dennis pointed out the manuals and log books show operations that
are way over square.
