I’ve read multiple times the big blocks can be a bit of a pain fitting cams with new bearings. Today I used the original 400 cam to test fit. Was a bit tight, to the point of needing a ratchet to turn it and back it out. I cut grooves in the old cam journals and used that to “size” my new bearings. I hope I’m not overthinking this and just being overly cautious but of course there were high spots that became shiny, and what seems like specs embedded in the bearings. I can’t feel the specs, the bearings seem smooth. At this point with the cam lubed I can spin it with a drill and walk it back and forth, so it seems to spin beautifully. If I need new cam bearings I’m totally ok with that, I’ve never had to do this before but it’s my first big block build and just haven’t ran into this in the past. Tightest bearing and worst looking one is the rear. Obviously grooved is front.Pics attached, opinions?
