I've found that about 325 kts indicated is about as fast as I can go in those planes without risking overspeed.

The speeds are listed in the _ref file accessed from the kneeboard; e.g.,

VMO - Maximum Operating Speed 340 KIAS
MMO - Maximum Operating Speed Mach    .82 Mach
Turbulent Air Penetration Speed    280 KIAS/.73 Mach
VLO - Maximum Gear Operating Speed    235 KIAS
VLE - Maximum Landing Gear Extension Speed    270 KIAS/.82 Mach

airbus a320= m.79
b737-300= m.76
b737-400= m.76
b777-300= m.84
b747-400= m.85
b737-700= m.78
b737-800= m.78
dc9-30= m.78
airbus a340= m.82

The above speeds are economy speeds, meaning that the aircrafts can fly faster than the mentioned mach numbers above.  :)
