Everyone had pointed out what they see.
What I also see is lack of oil to the cam bearing at startup. Now look at your main bearing oil feed holes and the alignment of the main and cam feed to the bearings oil holes. Can you show the oil feeds at the mains with the bearings out? Is this an early 360 by chance?
Slot the main bearing holes!
Any dark sections of the bearings are showing lack of oil.
Yes you have 600 open on the cam, but its starving at the main feed for oil.
Ps, sometimes the bearings have blueish to them in areas from plating. Make sure thats not what you're seeing on the thrust.
