The engine is the same on both tractors.  The block casting number won't 
tell you a thing.  You're going to have to get a good look at
the number on the torque tube.  Other than that, if you can post some 
pictures, some of us that are very familiar with AC stuff
can possibly tell by looking at it.  No guarantee.  One way to tell is by 
the rear wheels.  D-12's have a 2" wider stance than D-10's
but you would have to have the rears spun all the way out or all the way in 
against the locks and measure it to know.

The serial number is hap-hazardly stamped into the descending edge of the 
torque tube on the left hand side looking forward.
It will be something like D10 xxxxx or D12  xxxxx  with a space in between 
so you need to concentrate on the part of the number closest to the center 
of the tractor.  Everyone of them I've ever looked at read down hill from 
the center out so that you need to be facing the rear of the tractor to read 
it right side up.

I have an Allis tractor I believe to be a D10 or D12. I cannot read the 
identification on the torque tube, the motor id starts with
a 12.
My big problem is the casting on the block is LI6M, I cannot find this 
casting on ant databases I have found so far.
The Crankshaft and Head casting are correct for a D10/D12 tractor.
Crankshaft 277550
Head          AM4831.
The bore on this engine is 3.5 inch.
Can anyone tell me if this is the correct block for a D10/D12 tractor or 
what this block goes to.
I am getting ready to order some parts, but I want to certin what I have.
