A tid bit to generate conversation...
"If you examine the actual lift curve at the valves, a modern quick-lift hydraulic cam, in conjunction with high-ratio rockers and Rhodes Vari-Duration lifters, will approximate the valve-lift curve of a traditional solid roller up to about 0.600 lift."
Ken Crocie
And well noted there, a 'modern' quick lift hyd flat tappet cam.
Over about 0.600 lift, the big nose solid roller is king.
Again for conversation, you could go to Bullet Racing Cams and find a lobe that has the same 231 at .050" duration as the infamous Crower 60919 cam, yet with a high ratio rocker could be at 0.540" valve lift.
And with 21 degrees less seat timing !
