Or we can try to calculate it?
The Ford Engine makes 178 ft lbs of torque. Multiply by 6.4:1 1st gear gives 1139.2 ft lbs. Multiply by the winch ratio of 6.66:1 gives 7587 ft lbs. What is the diameter of the winch drum? If we hypothetically say the layer of cable is 8 inches from the centreline if the drum (divide by .66), that gives us 11495 lbs of pull.
The Chev engine will have different torque (170 ft lbs @ 1200) and gear (7.058 to 1) figures, and the actual diameter of the drum needs to be measured, but are we in the ballpark?
