You wouldn't need to change anything except gear mesh. Just drop it right in.

You would have to replace nothing other than the engine,
everything from the 21 will fit the 28 including the clutch and engine mounts

Keep in mind more displacement equals more power generally which increases the fun factor but also increases the chance of breakage.
So might want to check diffs for slop and stocking up on back up parts.

Might be a good idea to pull the transmission and diffs apart, replace worn bearings, and shim everything properly to ensure the "fun factor" doesn't turn into "oh crap!"
