Lucas Response To Zinc Additive

A couple of simple points not discussed yet. Mopar cams are failure prone because they have not been updated since the 80s. Cams are part of a system including the cam, lifters and springs. All components should be changed as a unit and compliment each other. Simple 30 weight oil and proper break-in procedures should suffice to prevent cam failure provided a quality cam from reputable manufacturer is used, Reground cams from Summit and JC Whitney and similiar sources are probably not the best choice for durability and longevity. Hope the original poster heeds the advice provided in the responses.
