What's LSA all about?
I'm just curious, the more I read about cams and these motors I hear alot about Lobe Separation Angle. I understand what LSA is in the design of a camshaft, but what can I tell about a cam from looking at the LSA spec? For example, what would be the difference in performance and, say, idle quality between a 112 and a 118 cam?
Understandably all of the specs of each camshaft are going to determine the performance and drivability outcome in the end; I'm just looking to become a well informed gearhead when it comes to knowing about cams.
Thanks for any knowledge you may have on this!

Take a look here. All you ever wanted to know and then some Cam Guide
Long and short of it, higher LSA (114+)=smoother idle, lower power band, slightly less power, better emissions. Lower LSA (112-)=lopier idle (is lopier a word?
) power shifted higher in rpms range, slightly more power, worse emissions. This is very generic. Read the link for more detail
