[AT] D10/D12

[charlie hill]

David there is a casting number located as you mentioned but
I've never seen any actual serial numbers on an AC block.  In addition
to what you said about the 160 engine, wasn't that 160 or something
similar available in some of the Gleaner combines?   Seems to me there
was a gas powered combine engine that was an easy transplant into
the D series tractors.

Externally that block is the same as the 160ci in the D15 series two,
making a swap possible. Internally they are different, causing the 160
rebuild to be a lot more expensive. I think there should be serial numbers
on the blocks (behind or to the rear of the carb) and casting numbers that
could help identify the motor's origin.
