The 87-91, known as the LN3 motor
close...well give you points anyway
87-88 is the VIN 3 or the LG3
there was a crossover year in 1988
88-91 is the VIN C or the LN3
and to got a little further into detail...
the LG3 is a 3.8 and the LN3 is a 3800.
The LN3 has alot of similarities to the L27 (Series I) so I like to think of it as the Pre-Series one.
Hope that clarified a little further.
Also. Pat, you said 87-88 on the LG3, do you know of any LG3s in an '88? If so there must be VERY few. Like VERY early model year.
