In the Ford engine repair manual for 1937 1947 Ford V8 engines it is listed as 65-70 ft lbs,I would imagine that didn't change for later engines or flywheels.

My 49 - 51 shop manual lists 75 - 85 ft-lbs. It did change for the later engines.

The flywheels got lighter but the torque required got heavier? Engineering.
