OK let's go with the formulas with this
Hp = torque*RPM/5252
Torque = HP*5252/RPM
According to my quick search for Merlin specs (in a P-51D) I found that it
produces 1740 HP at 3000 RPM, plug in the figures and we get:
Torque = 1740*5252/3000 = 3046 ft/lbs of torque
That and listening to WWII accounts of pilots saying they had to be careful
when taking off or they would flip their planes (Mustangs and Spitfires) due
to torque tends to make me think that these motors are/were very torquey
indeed.

I would never ask a pilot that! ;-) Actually my authority on the subject is
an Airframe/Powerplant mechanic so he could be wrong...
