GM 3.8 SERIES II L 67 SUPERCHARGED

The L67 is the supercharged version of the 3800 Series II L36 and appeared in 1996, one year after the normally aspirated version. It uses the Eaton Generation III M90 supercharger with a 3.8" pulley, a larger throttle body, fuel injectors, cylinder heads, and lower intake manifold 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. GM listed the engine output as 240 hp (180 kW) and 280 lb·ft (380 N·m) of torque, although broad torque span and perhaps conservative rating by GM due to the engine's temperature sensitivities have established a belief in higher actual output. Final drive ratios are reduced in most applications, for better fuel economy and more use of the engine's torque in the low range. Like most 3800 V6s, the engine is well known for its reliability and low maintenance costs. The engine is a popular choice for aftermarket modification thanks to its very strong internals and impressive power gains from basic upgrades. The engine was built in Flint, Michigan and was certified LEV in 2001.[WIKI]
