Check the post pinned at the top of the YZ400/YZ426/YZ450 forum. That will answer all your questions, and also kill a couple of hours reading it all. To quickly answer what you asked: yes, heaps of guys on here have done the 450 cam swap, and they all love it. :)

If you are asking if WR450 cam will work in WR400 the answer is yes. But I think most are putting YZ450 cams in.
It's not like before where you can just slip the cam 1 tooth to vary from YZ and WR timing. The autodecomp will only work in the timing (ie YZ or WR) that it was designed for.
