Other than crank and rods, do the blocks differ in any way? Are the rod and main caps, bolts and oil splash tray the same? Any other engine components different?

blocks are identical. you can throw a 4.2 block in your 3.8 and just change the upper manifold so that it will clear the mustang hood.

The 4.2 is identical, but it's equip'd with knock sensors. That's the only difference in the block that I know of. Depending on the year of your car, you'e going to need a difference flywheel, oil pan, oil pick-up tube, and balancer. Also the pistons are different.
