OK V.S let see if I can get this out. The lobe-seperation angle determines the relative phasing between the ex. lobe --the ex. event---& the intake lobe the intake events.(the over lap) The engine that has smaller lobe-seperation breath better at higher RPM more top-end HP & less lower end torque. The greater seperation angle better low-end breathing more low-end torgue.This is why some advance & tetard the cams & some run differnt rocker ratios on some motors this screws with the lobe separation.
