too mild camshaft
fishy68, the duration (amount of time that the lobe lifts the lifter, measured in degrees) is not effected by the rocker ratio.
The "duration" is simply a measurement of where lift starts and ends, not how much.
The "duration at .050" will change slightly because the rocker has a higher ratio and will have the valve open a little bit further, faster. Duration at .050" lift is a tool (so to speak) to give you an idea of how aggressive the cam lobe is.
The "advertised duration" is the actual duration of the cam.
The "duration" will remain the same while the lift increases across the board.
In other words, the duration of the cam does not change, the amount of lift does.
