Wheel Bearing Torque

I was wondering if anyone knows the correct wheel bearing torque for the
front disc hubs I just installed. I found a complete H-K front discs setup
off a '70 Dart Swinger and installed them on my '65 Dart GT. It was an easy
swap and allowed me to keep the SBP. My question is, what is the correct
torque setting for the wheel bearing nut? For drums, the manual says torque
to 70 in-lbs while rotating the wheel. I tried that, but the wheel seems to
drag too much. The instructions for after-market kits say to tighten the
nut until resistance is felt, than back it off until the wheel spins freely.
Any insight into the proper torque or technique for tightening the wheel
bearing nut would be greatly appreciated!
