Cm871 oil pressure issue after cam replacement

[wdm89]

Have a 871 that a cam and roller went bad on #5 hole. Replaced cam, rocker, oil cooler, and put rods and mains in. The rods and mains looked great and they said the cam bearings looked great also. (I didn't physically see those). My problem is when I brought it in the oil pressure was 38 down the road and 20-22 at idle. Now it is 14-18 and 30-35. Do you think I could have an oil pump issue? I was going to check pressure sensor and bypass valve but I don't see them being the reason since I didn't have problems before. Although I've seen weirder things before.
