I would'nt get to excited over this. I meerly suggested that you do an overall investigation to see if things look compatible. I'm not telling you that these 2 blocks are different because I don't know, however I would guess that there are differences due to the difference in years. The problem is that the ECU for the '98 will not provide the necessary hook ups and sensors for the '95 engine. So essentually you would need to swap over all the components that are different for the car to work properly.
On another note, The crankshaft numbers for the 2 different engines are not the same. I did look up a crank shaft bearing kit for the '98 and it will run you just under $200 at advance auto. This cost could be offset from the sale of the other engine and trans from the '95. Just a thought.

Option 2 would be to install verything from the '95 into the '98 including the wiring harness and ECU, but this may cause some issues as well.
In my opinoin changing the crank and bearings is the best way to go and sell the other car for parts to refund your expenses.

Perhaps someone else has done this change out before that could correct my suspections and could provide you with some better insite.
