Each of my eBay guides seems to refer to costly information that I didn't know and no one told me.

I have a 1984 Ford pickup that was losing a lot of oil out the main seals so it seemed like a good idea to pull it out, do rings, inserts and valves.   A machine shop that I lined up to do the rebuild recommended a local shop to pull and reinstall the engine. The machine shop furnished new gaskets and oil pump but not a new pick-up screen. Everything went fine for about 100 miles on the rebuilt engine until a piece of carbon (about the size of the white part on the head of a kitchen match) that was trapped inside the pick-up screen went into the oil pump. It stopped the pump, twisted off the oil pump drive shaft, galling and egging a couple of pistons. I had to pull the engine again and fix the damage.

The moral of this story is---
Replace the pick-up tube and screen every time you do anything to a Ford's lower end.  The tolerances are too close between the gears on the oil pump to allow anything to pass through.

I don't know if 351's have the same problem as 302's but they probably do.
