I've never had to spec a cam before, so are you able to elaborate a little please?

"more split between the duration" does that mean more or less duration, or something else?

With regard to the lobe separation, do I need to be looking in the 110-112 region? What does changing the lobe separation do and is it the inlet that is opening later, or the exhaust that is opening sooner or a bit of both if I reduce the LSA?

Whilst I'm more than happy to accept your experience, I do like to understand why I'm doing something.
