One problem appears to be that there were a lot of retrofits, and rebuilds. The engine codes LD-465 indicates a non-turbo, LDT-465-C is whistler turbo, LDT-465-D is non-whistler turbo, but the turbochargers were added on to reduce smoke and not to add power. I'm not sure if the Army may have added turbos to LD-465 engines during an overhaul or not. It appears that members here have traded 'c' turbos for 'd' and vice versa, depending on how they like the sound. The non-turbo and turbo models were both rated around 130hp.
Also GL does not do a great job of maintaining accuracy on their descriptions. The turbo will be on the passenger side of the engine, and a non-turbo wrecker or 5 ton will often have the air cleaner can out on the fender, but the Deuce tends to just have a 'mushroom' air intake exposed.
