The mother of all L-6 engines.
roducing up to 385 horsepower and 900 pound-feet of clean diesel torque
Well the inline six I drive everyday has somewhere between 600 and 650 hp. I don’t know how much torque. (Yeah it’s in the 03 Pete I drive. A Cat C15, model 6NZ. Probably the best truck engine Cat ever made. Most days it will average just over 7 mpg, which ain’t bad for a big truck)
