Narrow lobe center stuff sems to be way peaky to me, or at least what I have had experience with. OH yeah I think most SS stuff is going to have a wide lobe center too.

I have seen the wider LSA's have made more power and gone quicker at the track.





You are correct, a narrow lobe separation angle will make more peak torque in a narrower power range. A wide lobe separation angle flattens and broadens the curve.
Think of a narrow LSA representing a narrow peak and a wide LSA representing a longer mesa type peak.

The narrow LSA will give you a much higher number at a lower rpm, but the wide LSA will give you a higher number in the higher rpms and is easier to hook up because of less peak torque.

General Motors used this wide LSA/higher compression formula when building their corvette to get good mileage without sacrificing much performance.
