ld 465 1c

[2deuce]

Hello I just bought this old engine in the wood crate (partial rotted) with the numbers in the title. There is no turbo on it now and I don't think it was removed although the heater was removed. I'm curious if this engine is exactly the same as a LDT only without the turbo or is the compression ratio higher being there was no turbo. It has an engine tag that is totally faded and I don't see any ratings. Thanks

it is a non turbo engine, but otherwise is the same for any practical purpose. timing will be set differently.

So the internals and pump are the same as a LDT or LDS? Was the LDS built before the LD? If not could a LD be built for a 5 ton? If pump timing is unique to the LD because the engine ran without a turbo, adding a turbo to it should not be done?

Thanks

The LD and ldt are basically the same engine. The LDS is the 5 ton engine. It is very similar to the ldt but not exactly the same. I can't name all of the differences tho.

I can assure you that a LD CAN be run with a turbo installed and the fuel pump NOT retimed........My old truck had an LD in it with a turbo and the Injection pump was still timed to the LD settings........Now it also didn't have the same power as a LDT but it ran just fine.

My deuce had the LD-465-1c motor in it, until I added the turbo kit to it. I did a lot of research and found that it the only real difference between the LD and LDT motor is the addition of a turbo. The rest of the motor is the same. When I added the turbo kit I did not re-time the motor, I just bolted the kit on and let it ride. I noticed a HUGE reduction in smoke, and a small increase in power.
