Here's the article: http://wot.motortrend.com/next-gen-l...ch-280365.html
Sacrilege!!!!!! 
Wonder how hard that swap is gonna be? Plug n play with existing computers? Probably have to get rid of the displacement on demand and variable valve timing though. Then you run into the always-present limitations of injector sizing that direct injection guys get saddled with.
I see the following happening:
$800 camshafts
$500 springs
$1,500 injectors
$1,200 intake manifold to make a swap work.
But all worth it if going forced induction, as that sweet forged bottom end should be holding ALOT of power! GT500 guys will be pissed.
