Have you looked at he pricing of a bare bones A330f without refueling equipment installed, which is what there KC-30 is going to be based on vs the price of a KC-767 fitted out.
us dollars a330f——136.6-145.5 million (2003 figure) no ar
equipment installed
kc-767-—130-150 million outfiited with ar
equipment
must be able to discount them scarebuses with all that slush money loans.

http://en.wikipedia.org/wiki/Airbus_A330: A330-200F $175M (2007)
http://en.wikipedia.org/wiki/Boeing_767: 767-300F: $151-162 million (for the closest model to the 767-bitzer listed there)
