Thanks guys. All my Motors Manuals of that era call for only one full sized passenger car 240 and it is around 9.2 compression ratio. Shooting from the hip here because I don't have the book in front of me but I remember it is over 9.
Hate to admit it but back 30 years ago I actually worked of a nation wide fleet of Ford trucks and saw a lot of 240 and 300 engines. Other than providing a pay check I never got romantically involved with them and needless to say whatever I used to know about them I quickly dismissed and forgot. Lesson learned is don't burn your bridges behind you.
Drew, 2 parts stores both showed the B and E code listed under the Custom and the Galaxie. They are both full sized passenger cars. No truck of any size was in the list. Maybe a taxi or fleet version was offered and that is the difference?
I found the E code on the aluminum engine ID tag that is held on with the coil bracket bolt on the side of the head.
It's no big deal at this point but it is one of those things that might be interesting to know or need to know at some point.
