Much, much more complicated...
Perhaps. But not incomprehensible. I think that LSA is a useful metric in drawing a comparison between two cams with otherwise equal duration/lift specs. But I agree with MBHD - its best to have a cam ground to meet your needs.
In this light LSA simply becomes an outcome of timing-event choices for IVO/IVC and EVO/EVC.
Worth reading in this regard:
SpeedTalk-circa'09 Mechadyne In addition, with a custom grind one need not settle on a single duration. With a dual-pattern grind the exhaust duration can be elongated without necessarily inheriting more overlap (which is the case with a single pattern grind).
