Those Ford 7.3L diesels may have been a little on the noisy side, but they were (and still are) a great engine!
x2. I lost count of the number of times I saw people scurrying out their front door with their garbage bag on pickup day or children on school days as I approached and passed by their house. Besides the noise, the 7.3 also had a distinctive exhaust odor than that of most other diesels.
Great engine, but its Achilles heel was the Camshaft Positioning Sensor (CPS). I replaced it twice in mine and carried a spare... just in case.
