The 727 will not bolt up to the v10, you'd need the trans that came with the v10 or one out of a diesel.(The diesel and v10 share the same transmissions) As far as fitment goes, it all depends on how deep your wallet is. If you want to spend the money it will fit. I don't know about in stock form tho. Also, you'll need to put in some 1 ton springs up front to handle the extra weight, while your at it you might as well upgrade to 1 ton axles too to better handle the power of the v10. I think its a cool swap idea tho! Good luck!
