Dan, comes through again with the encyclopaedic brain about those K's

289 High Performance engines made between prototypes through preproduction and then production makes for a very complicated study. To have any clue how one might have been assembled in Cleveland you have to know the engine assembly date and the engine sequential serial number. Why? Because dates and serial numbers did not align in strict order of manufacturer. Ford made changes often.
Just for 1963½-64, quick ones that come to mind:
- More than one raw block casting was used to build 289 High Performance engine block assemblies.
- Two different ignition distributors.
- More than one revision level of secondary ignition wires.
- Four different carburetors.
- More than one carburetor spacer.
- Multiple PCV valve systems and valves.
- Engines for use with manual transmissions and late in 1964 production ones of automatic transmissions.
- Two different versions of special water pump assemblies (two impeller sizes)
- Three different cylinder head castings.
- At least three versions of cast iron intake manifold.
- At two different timing cover assemblies.
- More than one fuel pump and filter assembly.
- Two different starters.
To add to the fun dealing with these engines Ford did not service every part that went into them. I go looking in old Ford Master Parts Catalogs and some little parts are not in exploded view drawings or in service parts lists.
