Preferred Cam Timing adjustment

[racing97]

Cams will always have a certain attractive mystique about them interesting to note that the actual running timing will be at roughly .010 given the expansion at temp. Basically the important things for the designers of translating follower camshafts are the initial acceleration at the ramp when the rocker starts moving and the portion just after the nose dwell time where it starts acceleration again these don't seem to be altered much it at all in the cam on rocker arrangement as the constraint is the bearing housing which won't allow a larger lobe which limits lift to control the adverse effect of hammering the valve open and slowing it down to return it to the seat.
So duration and L/C are out parameters and we are probably lucky because fourth order polynomials really suck.
