It's the position of the mounts cast into the block with relation to the rear of the block. Like the earlier 4.3 you have to move the frame stands back.

The engine is something like 4.75 inches shorter, and the mounts are close to the same position in relation to the front of the block. For accessories.

Or atleast what I can see from the hood of both trucks I could check out.
