I've read on the subject that it may or may not increase the size of the component depending on how the process is done. None of that was even part of the discussion on the Z cam when I had that done.

Even some crankshafts were factory nitrided, my 302 Z engine was one.

We used to have marine cranks come through the plant. All of those cranks had to be subjected to a Kolene “bath” before they could be ground. Kolene are chemical salts that are heated to 750 degrees F. It is hot enough to “break” the chemical bonds of the nitriding. It does an amazing job, but I still have scars on my hands and arms from getting that crap on me. ALL aircraft recip engine cranks are nitrided. I have never seen it “chip” off one.
