Are you comparing 2 stock engines or the whole car? If so what year?
Just to expand on what Glen said,
3.2L engine management is relatively modern with no adjusting required. Get in, start the car and go. CIS not so much.
If this is a comparison of the cars that they come in, more info is needed, because there were huge changes over the course of the 3.2L years ('84-89). I don't think there were many big changes in the '78-83 years.
To get good info, you're going to need to give us more to go on. You "question" is kind of like
Water or beer. Any input?
Ford or Chevy. Any input?
This sort of vague post triggers many of us to imagine...
