That's not what he's talking about. The LSA has ZERO to do with how fast a rate of lift a camshaft is. He was talking about newer fast ramp style camshafts.
Pretty sure I mentioned it before, but early on when I was set straight on cams, was to use a modern grind vs 50 year old technology. I just brought up the LSA because he had mentioned it
I don’t know or speak cam-ese so I ask questions and gather the replies.
