The 3.8 L (3800 [[cubic centimetre|cc]]) '''LN3''' was an [[engine]] produced by [[General Motors|General Motors']] [[Buick]] Division. Introduced in 1988, 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. Designated initially by VIN code C, the 3800 LN3 was a major redesign, featuring changes such as a balance shaft, on-center bore spacing, use of a 3x/18x crank-trigger system, and other improvements. This generation continued in use in several GM products into the 1990s. It produced {{convert|165|hp|abbr=on}} and {{auto lbft|220}}. 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 (ECM reprogramming required). The L27 has a two piece, upper plenum intake and lower intake, the LN3 is all one piece. | The 3.8 L (3800 [[cubic centimetre|cc]]) '''LN3''' was an [[engine]] produced by [[General Motors|General Motors']] [[Buick]] Division.

===Future of the 3800=== | ===Future of the 3800=== | ||
Production of the renowned 3800 V6 engine was officially ended on Friday, August 22, 2008 when plant 36 was closed. There was a closing ceremony and speakers who extolled the virtues of the engine, but none that could give a definitive answer why they did away with it. Originally GM had set this date for January 1, 1999 {{correction needed}}, however due to the vast number of complaints from both investors and customers because of the popularity and reliability of the engine, the date was extended. At the end of production, the [[GM_High_Value_engine#LZ4|LZ4]] 3500 OHV V6 will replace the naturally aspirated 3800 applications, and the [[GM_High_Feature_engine#3.6|LY7]] 3600 DOHC V6 will replace the supercharged 3800 applications. | Production of the renowned 3800 V6 engine was officially ended on Friday, August 22, 2008 when plant 36 was closed.
