Solid vs Hydraulic

Is this true for solid roller cams too?So my solid roller .631 with 1.5 rockers is actually only .400 lift?I might have been mis-informed.:violent1:

.400 is the lift at the cam lobe...I just used that number cause it is easy...

cam lobe lift .400 x the rocker ratio. 1.5 = .600
cam lobe lift .400 x the rocker ratio 1.6 = .640

.631 / 1.5 = 0.420666667
