LD 465 question

My deuce has an LD 465 in it that was rebuilt in '86. It now has a C turbo in it. My understanding is that LD's did not have turbo's. I really don't think any of the previous owners did anything at all to the truck after it was surplused. My question is, did they add the turbo during the rebuild? I can't tell by the tag what exactly was done to the engine, I don't know what the codes mean.

The TD stamp is not a stamp but is casted in the block, recessed above serface. Its located to the right of the plate on the passenger side of the block. Towards the front. If I recall correctly from reading so much about these blocks. TD stands for thick deck. Indicating the type of heads you have. I don't think TD blocks were non turbos.

Thanks for the info, I was confused as to why it was designated an LD instead of an LDT. Maybe there was a batch of LD's built with turbo's and the TD blocks.

Definitely possible.... I think it was like that when the original owner got it also. If you ever take the turbo off. Just hope the bolts don't snap off. That's the biggest problem with that job. Otherwise, it will take a couple of hours if you drag it out.

My Engine-in-a-Can is an LD-465.
I have the prospect of acquiring a "blown-engine-Deuce" with an UNKNOWN powerplant. (95% sure it's a Multi-Fuel, 75% sure it's a Turbo)

Guessing that 'blown-engine" has a Turbo, and if I were to replace the "blown-engine" with my like-new engine, would I encounter any problems sticking the Turbo on the LD-465 ? Or should I be thinking about other considerations?

Thank you :grin::driver:

TD has nothing to do with turbo vs. non turbo applications.

After a certain point, they were all cast as TD's, to accommodate the higher torque ratings of the updated head gasket. I don't know they year this occurred but I strongly believe this to be the case.

Turbos were added to NA (Naturally Aspirated) engines to reduce visible smoke. If you get the turbo parts added to a standard LD-465, you now have an LDT-465 engine. Period. if you take the turbo off an LDT engine, you are left with an LD-465. The "T" was simply the way the Army could tell if the turbo conversion had been done. After a certain point, some time in the late 60's or very early 70's, they were all turbo engines leaving the factory.

Thank you :D

That reinforces my plan/desire/motivation to make an offer on the "blown-engine-Deuce".

"Roger that, we got a PLAN ! ! !"
