[[File:3800 LN3 89 bonneville.JPG|thumb|An LN3 installed in a 1989 [[Pontiac Bonneville]] with a later ICM and Coilpack upgrade instead of the original Magnavox Ignition System.]]
Introduced in 1988 and initially designated VIN code C, the ''3800'' LN3 would later be loosely considered the ''Pre-Series I'', although the older 3.8 SFI (LG3) was still available that year in some models. The LN3 was a major redesign, with a change to on-center [[Bore_(engine)#Bore_pitch|bore spacing]] (created by moving the left-hand bank of cylinders forward relative to the right-hand bank)<ref>[https://wbodytech.com/wiki/engines/buick-3800-v6/ wbodytech Buick 3800 v6]https://wbodytech.com/wiki/engines/buick-3800-v6/</ref> and the addition of a [[balance shaft]]. Other features included a 3×/18× [[Crankshaft position sensor|crank-trigger system]] and [[Multi-point injection|multiport fuel injection]]. This generation continued in use in several GM products into the early 1990s. It produced {{cvt|165|hp|kW|0}} of power and {{cvt|210|lbft|Nm|0}} of torque.

The LN3 is very closely related to the Series I L27 and Series I L67 Supercharged. In fact, [[supercharger]]-related hardware can be fitted to an LN3 without changing the cylinder heads. However, the [[Engine Control Unit|ECM]] would have to be reprogrammed. The L27 has a two piece, upper plenum intake and lower intake, the LN3 is all one piece.
