Degreeing the cam question ??

After you find absolute TDC and get your degree wheel mounted and a pointer set at TDC you calculate your duration from lift. If you have a hydraulic cam, roll the engine over until the lifter reads .006 lift and read the degree wheel. Then go to .020 lift and read the degree wheel. Then .050 and so on. Once you reach max lift and start down the closing side, take readings at all the lift points you did on the way up. Then it’s simple math.

You .006-.006 readings are the advertised duration for most hydraulic lobes. Then you have your @.020, .050 and whatever other lifts you measured durations.
