After just having a moderately frustrating experience with a parts supplier that I assumed should have known better, shame on me I came to find out the 1966 Mustang Ford Shop Manual does not necessarily contain the specifications for all of the 1966 289 engine configurations. In hindsight this makes some sense since the shop manual was publish at the start of the production year in August 1965 as a matter of fact and there were a number of changes throughout the 1966 production year.
To Fords credit they put an Engine Identification Tag on the intake manifold. This identified the exact configuration of each engine. In my specific case the tag indicated change 10 and I assume that meant it had all applicable changes through change 10. The question that I now have is does anyone know a website where there is a complete list of these changes?
I have also been told that the book Mustang & Ford Small Block V8 by Bob Mannel contains this information, but I have not been successful in finding a copy of this book in my local libraries. If any of you may have a copy of this copy and could scan and Email me the pages that define the 1966 Mustang changes I would be greatly appreciative.
