FOR INTEREST use some of the related calculators here with the specs on your current cam, then compare it to other lobes. Example change the seat duration (advertised duration) and/or lobe separation. See how it effects the effective compression ratio, dynamic compression ratio, cranking compression, etc.
( and yes different cam companies may rate their hydraulic lobes at different tappet lifts, but use their advertised numbers anyway, again for interest only here )
