differences between 2.6 and 2.3 engine blocks

differences between 2.6 and 2.3 engine blocks
from the little research I have done between these two engines, I have gathered that their bore is equivalent but the stroke is not.
My question is, is the different stroke achieved by having longer rods for the 2.6 or is it the crankshaft that is different ?
Also, it the height of the block similar or different ?

Blocks are identical, it's on the stroke that is different, the 2.6 uses a usual diesel stroke of 95.5 and I think the 2.3 is 92.7

This was all in the effort to create more low down torque together with the longer ratio gearbox and bigger wheels to improve fuel consumption and drivability.

RE: differences between 2.6 and 2.3 engine blocks
Yes, but my question was how was this achieved if the bore/block is identical. Is it through a different crankshaft, different piston connecting rods, or what else ? because there has to be different components in there for the stroke to be different. I hope the question is clear.

The crank is different everything else is the same except the pistons heads obviously to compensate for the compression ratio
