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 !

This is interesting, how much money could you save buying a flat tappet cam, suitable 1.65 rockers and Rhodes lifters.
Now would it make sense if you were planning to upgrade later to a roller cam what would you end up throwing away? Would it be only the cam, lifters, pushrods and valve springs? Would the rockers be reusable,?
