I did the McCauley 1A200DFA 82" X 44" fixed pitch on my 180HP C4F and there is no RPM Restriction in any range, nor any other range per TCDS's for prop. Most of the older props with the O-360 do have RPM restriction because of large mass of engine internals with a solid crank, ie, no vib damper system. Occasionally while flying I'll hit an area around 1800 RPM where a harmonic will set up and vibrate, but have found just a small touch of power either direction, gets rid of it instantly.
