I am trying to replace my engine in a 2007 trailblazer 4.2 liter engine but am told that an engine from an 02 thru 05 trailblazer 4.2 will not work. True or not?

I'm assuming that would be the only difference? Some mechanics have told me that they wouldn't work but could not tell me why? So replacing the computer would make the interchange possible?
