I've seen a lot of people say that they added a cam, but never see anyone share dyno results.

Now to decipher it.

The 4.0L OHV makes a 160hp. There's generally a 10-15% loss of horsepower to the wheels with a manual. In that case, I'm assuming you're 173-181 horsepower which is a gain of 13-21 horsepower. Sound right?
