The 3800 and 3800SC engines had a long life. Starting with the Gen I and then going on to the Gen II around 1995 and continued until 2004 when the Gen III engines made their debut, to the last run in 2008. If I did the math correctly the engine was used by GM for 13 consecutive years. Used in Pontiac Grand Prix, Impala SS and Buick Riverias (& Regals) . According to what I have read in Edmunds the combined total of Gen I, Gen II and Gen III engines numbered 25 million. Out of this number I would guess that about 1/3 or 8 million Gen II and GenIII engines were installed. A wild guess on the SC engines would still have the cars that used it in the 300,000 -500,000 range, maybe 4-6% of cars sold. Its a great engine and was very popular but I find it odd that here are so few 3800 enthusiasts today. It is an older engine but it can still perform well and because its not VVT , its easy to modify and tune. I just saw a you tube video where a guy rain a 9.87 earlier this year with a turbocharged version. So why is it that there are fewer enthusiasts today??? Where have all the owners gone?
