98-02
yes.
the 98s have diffrent harnesses, diffrent PCMs.... along with diffrent heads, coilpack mounting, ect.
the 99-02s use the same harness (atleast the same pinouts), same PCM (with slightly diffrent programming) have the better heads, later cars have no EGR and better intake, ect...
as far as whats a better drivetrain, get a 99+
as far as ease of swapping when you have the complete pullout: they're identical.

Yea, stay away from 98's if you can. They may be cheaper at first but will be more expensive for stuff like heads down the line. a 2002 would be the best since you would get a LS6 intake and more than likely a LS6 block.

its more a factor of the driver, mods, and THAT SPECIFIC CAR...
but since we're talking in general terms, you would want the better parts, as you have a better chance of making thoes fast then a oddball factory freak.
