that looks iffy at best, the sleaves might have shifted so they will have to be re-honed and i don't know how that would workk with the crack going throught the entire length of the block.

Being an engineer I have a tendency to look at issues like this from a different perspective...the question I have is "why did this block crack between the cylinders?".
The only answer that I can come up with is that there was a bad pour when the block was cast. If the molten aluminum does not flow into the space between the cylinder liners or if it cools prematurely then there will be a weak point.
If I were in your position I would use this block for a MID sleeve project or perhaps sell it to someone for that purpose. While I have done some fairly complex welding I don't believe that I have ever seen a weld done on aluminum when it is this deep and bounded on both sides by steel.
Keep us posted on what you finally decide to do with this block...

What you will have to do is cut the 2 sleeves out and then cut the crack out to the water jacket and the weld it all back up and resleeve it. Not hard just time consuming. I have seen it done on various aluminum engines many times.
