5.3L Cam Install
 

I'm trying to install a new cam in a 2003 5.3L. I installed new early 2003 cam
bearings with no problems. When I tried to install the new cam, it won't go past the 3rd journal. I replaced the bearing again, no difference. Any history of this ?

Clevite SH1814S Bearings
Jegs Cam 555-200578

Thanks
