Also, if the engine has DOD (Displacement on Demand) or AFM (Active Fuel Management), blocking off oil ports or switching to a non-DOD valley cover is necessary. These points are critical because they remind me that while this kit is comprehensive, I need to verify my engine specifics and be prepared for some additional parts or modifications. This transparency helps set realistic expectations and avoid surprises during installation.

Overall, this Dynosty BTR Truck Norris Cam Kit stands out as an excellent option for those wanting to enhance the performance of their LS-based engines without piecing together parts from multiple vendors.
