Mis-aligned Cam journal
I have an I6 short block that failed. When the 'pro' was building it, he had a problem installing the cam. One of the journals was slightly mis-aligned, and the cam would not enter. Finally he used a fine emery cloth to lightly sand the bearing, and the cam slipped in.
Is this common? What should have been done? If I send this block to the machine shop (again), is there a procedure to rectify this problem?

On some engines, not sure about the 300, you can align bore the cam bearing bores and press in oversize (OS on the OD) bearings.

Words of wisdom, no doubt. He was a friend in need. I'll always remember the sound of empty beer cans hitting the concrete floor as he worked. Never a good sign. Somewhere in the background I should of heard my dollars fritting away too.
