OM617-vs-2 stroke diesel
Detroit's use exhaust valves. Turbo charging is not required, but a blower is, at least on a detroit. A turbo is often used in addition to the blower. And they do make great truck engines.
Must say that if only two exist of whatever you have I would not use it. Keep it as an antique engine and then use the 617.
