The LB7 Duramax was introduced in 2001 and was an immediate success, earning best in class in multiple categories and even out performing the comparable gasoline power-plants. It was initially rated at 235 horsepower and 500 lb.-ft. of torque which was right in line with the competition, matching the same power and torque as the intercooled 7.3L Power Stroke Diesel and the 5.9L 24 valve Cummins. The common rail injection is what really set this engine apart from the rest, aside from being smoother and quieter than the competition, it was easy to add power!
