[350TSS]

One other issue I encountered today which I initially thought was terminal was that the "drop" of my dial gauge is less than the lift on the cam lobe. This means that I cannot measure the maximum full cam lift.
However, I think this is actually a good thing.
At the peak of the cam the difference in movement of the valve opening shim between say - 5 degrees and +5 degrees will be very small and even less so pro rata between -2 degrees and + 2 degrees of crankshaft movement simply because the cam profile has to be less aggressive at the point where a direction change in the movement of the valve train is intended/imminent.

Provided the cam profile is symmetrical (and I think most are because the manufacturing process so dictates), then measuring the lift and the recline (some crank rotational distance from the maximum lift) at the point where the cam is more aggressive provided the results are divided by 2 will give a more accurate result. I think????
