The all new Eco-Boost V6 producing over 600HP. But According so some rumors at the Ford GT forums by some members *i hang around there* the car is not only going to come equip with an Eco-Boost V6, it will also have a Flat Plane V8 Engine i don't how or who spread this rumor, but they say he is a Ford Engineer and owns a 2005 Ford GT who knows ... Anways The Shelby GT350 also comes with a 5.2 liter Flat Plane V8 at 550HP. So i do think it will be later showned just as how they did with the GT350R. I don't know when Ford will reveal the V8 Version, but all up to now the V6 is what we have. I have to say it's amazing. To me Ford has always been different than it's competitors like Chevrolet and Dodge. And now i don't what to say. I am left without words.
