660 lb-ft of torque and 365 bhp ensure that if you're behind the wheel of a new Heavy Duty Sierra, you won't be looking longingly at anyone else wishing you had more power to move your load. Those numbers give it a 10 lb-ft advantage over its Blue Oval and Mopar rivals, and a 40 bhp advantage over the Ram and 15 bhp over the Super Duty.
Best of all, the motor is covered by a best-in-class 5 year/100,000 mile warranty
Our take? Those are some serious, serious numbers.
