Built for incredible low and mid-range torque, this cam is the perfect choice for 5.3L to 6.0L truck engines when towing and hauling.  Less aggressive than the ZL9, this cam with its .525" lift, works well with LS6 springs and duration of 202/216 keeps the intake system within the factory rpm range and delivers good economy and road manners.  Good for 30-35 hp with lots more torque.
