It'll take more than the cam specs to calculate DCR. Rod length, bore, stroke, piston cc (dish or pop up), piston deck height (above or below deck), head gasket thickness, head gasket bore, and combustion chamber cc will be required to perform the calculation. I'm sure there are online DCR calculators if you do a search.
Edit: I found one for you, it just requires registering.

Looks like they want a few more dimensions I didn't mention like piston to bore clearance and top ring land height...they're going after every little fraction of a CC they can!

daym Glass, I got all the #s on the cam(more than I thought ever possible) but I dont have the other stuff. I guess just to compare apples to apples I would use the OEM numbers for all those parameters but I have no idea what they are.
