Just curious. My LLY through a Carrillo rod through the block and I need to replace the block. Can I use an LBZ block with LLY heads, injectors, CP3 ,glow plugs, etc.?
LLY to LBZ
- Thread starter messejme
- Start date
This may help. I am pretty sure any block up to 2016 LML are interchangeable.

Interchangeable Dmax parts
Not sure if this has been listed anywhere as a sticky or not but thought it might be worthy of one. If it has been covered before I appologize. I think it would be great idea to list what stock parts can be swapped over from one generation of Duramax to another to get performance increases that...

Sure can, just use your LLY reluctor wheel and you are good to go

They are interchangeable going backwards but not using a older block in a LML truck.

Not sure why one would want to as the LML block is Superior, but why couldn't you?
Motor mounts won’t bolt to older blocks. They don’t have the bolt voss on the older blocks.

That seems like an easy modification to overcome but like I said not sure why one would want to. Besides the EPA I'm sure would frown on older power train in a newer vehicle.
This is true. I put my lly built motor in my lml. The passenger side motor mount didn't bolt up. I have a 3/8 plate bolted to the block to move my motor mount foward
If you get a new set of GM replacement mount they are drilled with both patterns. Just noticed the relatively new mounts on my LBZ have the five holes.
