Although each cam company employs its own cam-card format, any one of them will tell you everything you need to know about your cam. This Lunati card spells out this cam's LSA, intake centerline, each of the valve-opening and -closing events, valve lift, advertised duration, and duration at 0.050 inch. The valve-adjustment spec shows zero, since this is a hydraulic cam; in a solid-cam application, the amount of lash needed would be specified. All manufacturers will recommend the appropriate valvesprings for each application; Lunati adds this information to the cam card.
