Thought I might as well start a thread to collect the findings of different threads related to running changes in one place like I started for the 66 San Jose built cars. Will continue to add suggestions for individual running changes here in this thread while will be the basis for related link threads focused on each individual subject. Remember to keep these 65 San Jose focused here please note 64 1/2 cars or ones from other plants.
To keep the thread from getting too long or out of hand please don't post that you found this version or that on car 5R07C2345xx (for example). We can save that for the research period and for the individual change threads. Just trying to identify the features during this first effort. Will break out the findings by plant of course. Hope we can work through other plants also. Since this is likely to get to be a very long list I think that unlike the 66 version I will break the lists out by general area of the car to keep it a little more organized. We'll see how that works.
If you post suggestions for items to be included I will delete your posting after it has been incorporated rather than let the add to post run on for pages
Drivetrain- Engine - Most of these are more related to when the engine was assembled and shipped than to a specific date the change would have taken affect at each assembly plant. Those details can be found in the book
Mustang and Ford Small Block V8. But to help we'll list a few more commonly asked and those visible on a fully assembled engine

Water pump and timing cover - Change from aluminum water pump to cast iron version. Change is identified by a L-8 on the aluminum engine ID tag. rather than by VIN.

E2-
Road draft tube usage - Change of location of draft tube and transition from the tube to PCV.
