Camshaft throwdown

After lash the mechanical will have about the same lift as the hydraulic as they both are .500” lift rule cams, you’re going from a 108 LSA to a 106 (both recommended on 106 ICL) not sure how the actual “advertised” duration at various measuring points compare as well as the duration @,050” The hydraulic is supposedly good for 1/4 mile flat tracks and the solid for 3/8 mile flat tracks. So on the surface the solid should pull (rpm) a little longer, just how much harder depends on actual timing and where it’s installed compared to what you have now? Have you measured the current cam to see actual opening/closing points?
