I think the torque value alone is in the 300 ft lb range.
I've seen guys with LONG 4' extension pipes torquing the bolt.
We did a write up on newer I-5 motors (200 20V) here:

Some specs there. Photos of the tools etc. There is a math formula to
determine force x distance. Google conversions calculators
