The classic uses standard speeds.
Flaps up 210
Flaps 1 190
Flap 5 180
Flap 15 150.
Depends on the weight schedule. The above quoted speeds are for 53,070 kg and below. However, assuming that by now all 737 Classics have the required rudder mods installed, the Flap 5 block speed is 170 knots at 53,070 kg and below.
