HFT vs SFT Cam Identification
Yes on the ramps. the solids had a run up ramp and then the lift, same long ramp on the back end. the Hydro cant have a run up (they just pop up and down and then flat line for ~220 degrees of cam rotation) as the lifters will pump up to lowest point of lobe and stay pumped at that point so a run up ramp will bleed cylinder pressure with a very slight valve opening.
