Ok, you read alot about solid roller cams not liking to idle much, and that the lack of oiling from constant low rpm can cause lifter failure(along with high spring rates and lifter skidding). Plus reduced spring life from the agressive lobes and high lifts. But what about constant higher rpm use? How do they like or dislike highway driving, say at around 3000-3500rpm constant? You never hear about that end of the question.Thanks.
