This is an odd one. Turns out 1.868-1.869" are the acceptable dimensions for the journals on the cam. I measured my old cam and it cam out to about 1.859. I pulled the timing gear on the old cam and saw a 010 stamped on the fromt of the cam. Turns out the cam was ground .010" undersized and undersized bearings were used in the block. Kinda weird no?
