I could use some help understanding lobe separation angle. Not what it is. But why, for example, a cam with a tight LSA creates more low-end torque while a cam with a larger LSA makes power across a broader RPM band. I've looked for a simple, intuitive, explanation of this but haven't found one. The Pontiac engine books I have only go so far as to characterize the differences, not explain what's happening in the engine.

Is there a reference book, online resource, etc. that explains this? This has proven to be the biggest mystery to me in my effort to better understand camshafts.
