I'm going to pull the engine in my Duster to freshen it and I was wondering. Do you guys ever check your cam for wear? I would assume the lobes will wear with age but I have been running this Isky solid cam with the same lifters for 12 years now! This is the second engine its been in. It was in the dart when I broke a rod and I put it in the Duster when I built a 360 stroker in 2008. I guess I'm living on borrowed time I avg over 150 runs a year. What are your thoughts?
