Any idea what year so I can find parts and all that
The only real difference between the 6.9 and 7.3 is the head bolts and other mnior internal changes.
6.9s were put in from 1983-1987.
You also can't put more than about 6 psi of boost through a 6.9, if you go to turbo it. More than that needs a set of headstuds.
I kind of get the feeling as well, though, that you'll get slightly more fuel economy with the 6.9... and cavitation isn't really an issue.
No, not with the door sticker.Thanks for all the info but I feel like this adds to my theory that it came from the factory this way like the motor was left over inventory they were trying to get rid of I've work for big production plants and seen stranger
