Pre '89 NG motors v. post '89 NGs

[AUDIDUDI@delphi.com]

I'm in the market for a used NG code 2.3L motor and noticed that, according
to the Bentley manual, there are two versions of this motor ... or at least
two different cams were used, depending upon the build date.  They're rated
at the same power output (130hp/140ft.lbs) but I assume one of them must be
stronger than the other ... I'm guessing the later version but don't have a
clue about it otherwise.  Any input/idle speculation/informed opinions/wild
rumors will be greatly appreciated (as will a great deal on a used motor!).
