Default Re: Was there a 4 cylinder motor in 34

Ford's part numbering and identification system was always evolving. The single alpha letter was to designate a change to that part. Ford later changed the design change indicator as a suffix at the end of a complete part number. The heads for the V8 sometimes had the single digit alpha letter, for example the ones in 1940 or so that just had a big A on them. Then on the post war engines they evolved to 59AB which gave both the engine designator and the design change.
