I.D. this engine?

Is this a LDS? It is in an M51, it is not the original engine. I think the truck was a gasser.

If its stock, it "should" be an lds.

Has the gated turbo that came on LDS motors.

I don't go with that as an indicator. Reason being I've had LDS engines with and without the wastegate. I've had some that I picked up at the DRMO and they had LDT C turbos on them.

I agree! It could have easily been put back on an LDT engine. There is even that offset adapter to put "C" and "D" turbos on 5 tons and hook up to the exhaust. You sure won't see that turbo on a deuce, not without exhaust mods!

LDS LDT C D.......WHATEVER! Just imaging how surprised that bird is gonna be when it lights off!

haha

Aaron, I was thinkin the same thing! Kenny, how can you tell the waste gate is there, by the intake side? Ididn't think it looked like the one I got.

The neck from the manifold to the turbo tipped me off.

Hi,
To me, this looks as an LDS since the oil level dipstick is at the end of the engine (LDT has it more in the front). i have the same problem with my M54A2 where the engine has an ID tag of a LDT 4651C and a C turbo . The LDS has the oilpan inverted compaired to the LDT

The neck from the manifold to the turbo tipped me off.

The intake manifold adapter is the same on the LDS and the non-turbo deuce engines.
Couldn't find the original photo, but compare the images below. Note the location of the waste gate.

Yup, that first one is the one I have. I was wondering how I'd find the correct intake horn, thank you Bjorn!
