Time to build oil pressure

...

Now here's hoping the County oil pump from Moss is better built than the County water pumps....

For your sake I hope so, but wouldn't bet on it. After my experiences with their water pumps I refused to buy their pistons, even though they were the only ones I could find off-the-shelf in the diameter I wanted.
 
Do not trust a County oil pump. A few years ago I bought a new County oil pump for a freshly rebuilt race motor. A flyer came with the pump and warned not to open the body of the pump and stated something about "mating of the precision gears". Well, that sounded like nonsense to me and I opened up the pump. I discovered a huge void in the casting.... about the size of a dime. That pump never would have created any pressure in a million years if I would have installed it.
 
It's been a couple years, but when I rebuilt my BJ8's engine I priced oil pumps and found, IIRC, that the Denis Welch 'High Capacity' pump was not much more, and perhaps less with the exchange rate at the time, than pumps from the 'usual suspects.'
 
I bought a DW pump when I replaced mine several months back. The oil pump is the engine's heart and if I were having, for example, a heart valve replaced I would go for the gold!
