L275 & L235 engine block swap (D1302, D1102)

[LeadHead]

I have an L275 with a 3" hole in the side of the block (previous owner-induced). I've been planning on patching the block because the crank appears to be fine, but I recently found a L235 engine block that can be had for a good price and I want to know if it can be used, after a little work.
From what I've heard, the D1102 (L235 block) and the D1302 (L275) share the same crankshaft and connecting rods. The engine specs state that the stroke length is identical on both engines (.323) and the bore diameters are .299 and .323, respectively. I have been told that all the mounting holes (internal and external) are compatible between the two, but can someone verify that for me? Considering the fact they use the same crank and rods, the cylinders on the D1102 should have much thicker walls and would be spaced the same as the D1302.
Is it possible (read cost-effective) to take the D1102, remove the cylinder sleeves, have a shop machine the bores then remove the sleeves from the D1302 and drop them in, then bolt everything else up and be good to go? The D1102 crank is not present but my crank seems to be fine and is what would be going into the D1102. What problems should I worry about, or is this job simply not recommended for some reason?
Also, after running this idea past my ASE-certified mechanic buddy, he wanted to know if the sleeves are the O-ring style or pressed in. Is it even possible to remove the sleeves without damaging them?
Thanks in advance for any help that can be shared.

Also, is there ANY chance that the cylinders in the engine blocks are the same, but that the D1102 sleeves are simply thicker than the D1302 sleeves so that maybe it wouldn't need to be bored at all? Long shot, I know, but....
The million dollar question is whether all the other mounting holes for accessories are the same. Injector pump, water pump, etc....

Hey Leadhead: Did U ever get yer D1302 running, Merv

It got shoved to the back burner, partly because of finances and partly because of lack of opportunity to get it done, Merv. I'm hoping to be able to do something with it by summertime, though.

Any update on this. I have an L235 than needs an engine rebuild. Would rather spend few extra dollars and rebuild this to a higher output engine.

What else is different/same between the D1102 and the D1302? What about the 1402?

Well guess LeadHead is no longer on the board. Does not answer PM's either soooooo.... anyone else have any insight on differences between the xx02 engines?
