The LDS-465 engines were out of the five ton multifuel trucks. They have been put into 2 1/2 ton trucks by the military for many years when the truck is rebuilt.

The A1's had Continental LDS-427-2 ( built under the MANN diesel whisper engine licence ) Multifuel turbo engines, and 5th gear was an overdrive.The engines were not reliable. A2 trucks received the LD-465-1 non turbo, keeping the OD transmission of the A1s. Through the years the trucks were upgraded to LDT( turbo clean air)-465-1A, B, C. The turbo was added more to clean up the very black exhaust on the Non Turbo engines, than to add power, the HP was only raised from 130 to 135 HP. The LDT-465 D was the last version of the Multi Fuel, it had a Quieter Turbo ( non whistler )better head gasket sealing and head cooling.
