Some Detroit Diesel stories.
I drove several trucks with DD's including a couple of GMC 9500 day cabs. One was particularly horrible. For one, it had a 318 with the 50 injectors (I think) so it was a gutless wonder. With twin stacks mounted to the cab rather than the frame, it was horrible. I stuck around about a month.
I used to get my doors blown off of my F model Mack with a 318 (Big injectors, loud) by this Astro 95 with a V12 Detroit. That thing would run.
LOL, I was cruising along in North Carolina one time. I come up on a cabover along the road with the cab jacked up, two guys working on the Detroit. They had a head off, likely swallowed a valve. No service truck around so I guess that they carried parts with them just in case...
