History of the Buick/GM 3800 V6 Engine
Introduced in 1995, the Series II is quite a different engine. Although the stroke for the 3.8 L engine remained at 3.4 in (86 mm), and the bore remained at 3.8 in (97 mm), the engine architecture was vastly changed. The piston connecting rods were 1 in (25 mm) shorter, so the crankshaft was redesigned. A new intake manifold improved breathing, and a new cylinder head had larger valves. The result was 205 hp (153 kW) and 230  ft??lb (312 N??m) of torque, better fuel economy, and 26 lb (12 kg) lighter overall weight.

The 3800 Series II was on the Ward's 10 Best Engines list for 1995 through 1997.

The 3800 Series II, naturally aspirated, was used in the following vehicles:
  • Buick Park Avenue
  • Buick Le Sabre
  • Buick Regal
  • Buick Riviera
  • Chevrolet Camaro
  • Chevrolet Impala
  • Chevrolet Lumina LTZ
  • Chevrolet Monte Carlo
  • Pontiac Bonneville
  • Pontiac Firebird
  • Pontiac Grand Prix
  • Oldsmobile Eighty-Eight
  • Oldsmobile Intrigue
  • Oldsmobile LSS
  • Holden Commodore
L67 Supercharged
The L67 is the supercharged version of the Series II L36 and appeared in 1996, one year after the normally-aspirated version. It uses the Eaton Generation 3 M90 supercharger, with different throttle body, fuel injectors, cylinder heads, and lower intake than the L36 uses. Both engines share the same engine blocks, but compression is reduced from 9.4:1 in the L36 to 8.5:1 for the L67. Power is up to 240 hp (180 kW) and 280  ft??lb (380 N??m) of torque. Final drive ratios are reduced in most applications, for better fuel economy and more use of the engine's torque in the low range. The engine was built in Flint, Michigan. The engine was certified LEV in 2001.
