L67 Supercharged
The Series I Supercharged engine went through many internal changes and the horsepower changed rapidly between the time it was introduced and the time that the Series II L67 was introduced. The M62 supercharger was manufactured by Eaton, exclusively for the GM 3800 engine. HP was rated at 205 for 1991-1993 engines (models vary), and 225 for 1994-1995 engines. The additional horsepower and strength was gained by using six bolt main bearing caps, a roller camshaft, semi forged bottom end, larger throttle body, roller rockers and epoxy coated supercharger rotors, improving efficiency. The 1994-1995 utilized a 2.85-inch (72.4 mm) pulley versus the 2.55-inch (64.8 mm) pulley used on the 91-93 supercharger.
