New cam?
Thinking about getting a bigger cam for my 99 grand Cherokee 4.7. How would I reprogram my computer for the bigger cam? Please let me know if you have done this before! Would be a big help!

Also it's cams. You have two you're gonna need to change.

It's not a DOHC. It has a single cam.

The 4.7's are a dual cam

You are partially correct. It's a SOHC. One cam per head. Two heads=two cams.
