L67 Series 2 3800 Supercharged GM Engine Blueprint Series T-shirt

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 in (97 mm) pulley, a larger throttle body, and different fuel injectors, different cylinder heads, as well as different lower intake manifold and pistons 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 (179 kW) and 280 lb⋅ft (380 N⋅m) of torque. Final drive ratios are reduced in most applications, for better fuel economy and for improved use of the engine's torque in the low RPM 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
