Im no expert on 2V motors, but I think the blocks are about the same. One thing better about keeping your 96 block, with the PI heads, you will have slightly higher compression so this might produce a bit more N/A power than if you just swapped in the whole motor. It would probably be much easier to swap in the complete long block though....

do a compression and leakdown test on both, use whichever is healthier.

The Windsor block is stronger, I think that's what the 96's are but Im not completely sure, look at the side of the block. If its a Windsor block take the heads off of the 04 and put them on it.
