yes, i dont believe honda has changed a single thing on the 400ex motor except for adding reverse to the newer ones which shouldnt impact the top end fitting.

if your just swapping a top end onto a complete bottom end then its not much work at all. If your talking about spliting the bottom end open and replacing the internals (Crank,bearings,gears) then its a much more involved job. Anything can be done with a manual tho!

why do you want to do that
Only difference is the 08+ topends dont use a decomp setup on the stock cams.
