Camshaft Lobe Separation Angle — A Practical Primer
What LSA changes in idle, vacuum, and midrange for dirt, drag, and street motors.
Lobe separation angle (LSA) influences overlap. Tighter LSA can add midrange aggression and a lumpier idle; wider LSA often aids vacuum and street manners.
Duration and lift still rule the power curve — LSA is one lever among many. Match the cam to heads, compression, converter/gear, and how you race.
