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.

A smaller 3.3 liter ''3300'' was introduced in 1989 and produced through 1993. It was effectively a lower-deck version of the 3800, with a smaller bore and stroke of {{cvt|3.7x3.16|in|mm|1}} for {{cvt|3341|cc|L cuin|1}}.<ref name="AR92">{{cite book | title = Automobil Revue 1992 | editor-last = Büschi | editor-first = Hans-Ulrich | publisher = Hallwag AG | location = Berne, Switzerland | language = de, fr | page = 433 | volume = 87 |date=5 March 1992 | isbn = 3-444-00539-3 }}</ref> Like the 3800, it used a cast iron block and heads, push rods, and hydraulic lifters.  Unlike the 3800, however, it used a batch-fire injection system rather than sequential injection, as evidenced by the lack of a cam position sensor.  It also did not have a balance shaft. Power output was {{cvt|160|hp|kW|0|}} at 5,200&nbsp;rpm and {{cvt|185|lbft|Nm|0}} at 2,000&nbsp;rpm with a 5,500&nbsp;rpm redline.
