"LSA is frequently the least understood and most perplexing factor of camshaft timing. Any change from increasing valve overlap, advancing the intake lobe, retarding the exhaust lobe or any combination of these can change the lobe centerline. Each change made offers contrasting aspects that should be considered both independently and as one. A wealth of complex information exists on Lobe Separation and Lobe Centerline which is much more than can be covered in this article."
