starting with the HP correction factor.
** At 3,800 RPM, when your 400-CID engine is producing 445 pounds-
feet of Torque, it is also producing about 322 HP at the flywheel.
estimating flywheel Torque — Based on HP and RPM
If you know Horsepower output at a specific RPM, you can calcu-
late Torque at that same RPM.
In this example, your 400-CID engine produces 366 HP at 5,400
RPM. Calculate the Torque for the same RPM.
