Intake - LXL lobe - 222 deg. @ .050" - .602" lift with 1.7 rocker
Exhaust - Xtreme RPM LS1 lobe 236 deg. @ .050" - .578" lift with 1.7 rocker
115+3 LSA

You can get all this information from here: https://www.compcams.com/lobe-catalog and searching the lobe numbers (top of cam), the intake lobe is 13157R (roller) and the exhaust is 3705R (roller). The HR115 is a hydraulic roller with 115 LSA, the "up arrow" 3 means it has 3 degrees advance ground in it so the intake centerline would be 112. The "CC" is Comp Cams. The number on the bottom are core and serial numbers specific to this cam.
