Hello all; I'm new to the forum and fairly new to ford diesels as well. \
I'm working on a project truck and have the option of using a 6.9 or a 7.3. Already have a sidewinder turbo and intercooler along with an 88' 5 speed tranny/4.10 rearend. I have heard that the 6.9 has thicker cyl walls, thus making it more durable than the 7.3, but that the 7.3 has other upgrades, such as better glow plug circuits, etc.
I'm looking more towards getting better mileage then power and was wondering if choosing the 6.9 over the 7.3 would make a difference?
Thanks in advance, Chris
