"The 4.0L has a 0.125" larger bore and the block is about that much
wider
on the right side (87-90 258 blocks use the same outer casting and
are
also wider)."  Swygert, Francis G MSgt 436 CES/CECM


As to the inner castings, since the cylinder locations are same as
the 4.0 > are the cylinder walls thicker since the pistons on a 258
are smaller diameter ?
-----------------------------

As far as I know the walls aren't thicker, the water jackets are wider.
No point in wasting a couple pounds of good casting iron for nothing!
