Pontiac brands like the Bonneville used the 3.8L engine for the first time in the year 1982. The famous 231 cubic inch model was introduced as a lightweight V6 block. This was quite a change compared to the 5.7-liter V8 that was offered in the mid 1980s. The regular FF body style accepted the smaller block as well as the 3-speed TH transmission.

From 1982 to 1986, the regular series 3.8-liter was utilized. When the platform to the H series was unveiled, the block changed in diameter and horsepower. The H body styles were in production until the 1991 year. This gave more room to the LG3 and LN3 aptly named 3800 V6 builds. The performance upgrade along with the 440T transmission was well-received by consumers.
Pontiac Bonneville 3800 Series II
GM started a long trend of developing supercharged motors in the year 1992 until the termination of the Bonneville in 2005. The RPO codes for the units leading up to the 1999 Pontiac Bonneville 3.8 V6 engine were L27, L67 and L36. These were named series I and II. Each model had a measurable increase in performance.
Because gearboxes were renamed by GM, some of the earlier models were not found in the late model Bonneville vehicles. The electronic controlled 4T60 and additional builds were paired with all of the series II and lower 6-cylinder blocks. By the time of the 10th generation of production, GM had started to mix in the Northstar motors used in Cadillac cars.
This change put an end to the Pontiac Bonneville 3.8 V6 engine in the 2005 year.
