Just to clarify the history of my engine as I understand it as there seems to be some confusion or misunderstanding about it.
Car was bought in 1959 with unknown history and was driven only a mile or two a day until 1975 when I parked it by Mom's house where it sat for 31 years.
In 2006 I towed it to my house to begin a minimal restoration limited to getting it running, pass safety inspection and licensed, painted and reupholstered.
9 days later, after only changing the oil, replacing the battery and cables and starter solenoid and putting an acceleration pump in the carburetor we started it up and drove it for 10,000 miles before having it rebuilt in October 2009. (Here's the movie of starting it up that has had just short of one million views on Youtube:

When the rebuilder opened up the engine he found everything original except a couple of valves that had been replaced. The bearings had the original date of manufacture on them - August 1947. The crank pulley was loose on the front end of the crank so he decided to replace the crank with another used one that he machined and replaced all bearings when rebuilding (I still have those original bearings and crank). He also informed me that I had been running the battery hooked up backwards (I wondered why my ammeter read backwards) and that my carburetor was not the original for the engine as it was a Stomberg 97 last used in 1937.
He machined all surfaces and replaced all pistons, rings, bearings, valves, and I don't know what else as well as rebuilding the transmission and drive-line.
I kept everything that came out of the engine as I've saved everything that's ever come off of the car for historical purposes.
In May 2013, after driving 30,000 miles the #3 piston came apart. (Story here:
https://www.fordbarn.com/forum/showthread.php?t=104413) I took it back to the same builder who redid the whole top end including sleeving piston #3 and boring all pistons out to a larger size so he could put in all new larger pistons. He also replaced the valves and split valve guides with later solid ones. I don't know that he did anything with the bottom end as far as remachining any bearing surfaces nor replacing bearings. I'm pretty sure that he didn't since they were all still OK.
The rest of the story is this thread with the bearing problem now after another 20,000 miles, total of 50,000 since first rebuild.
Hope this helps resolve some confusion.
