Over on Facebook today several photos were posted of Ford Racing engineers testing the 2013 Mustang Cobra Jet at Milan Dragway. I guess this is their way of confirming the Cobra Jet for the 2013 model year. In those photos we can clearly see a 5.0-liter V8 under the hood of one of the test mules. So you will now have the option of purchasing 2013 Cobra Jet with the Coyote V8 or the 5.4-liter V8, nice choice to have. Check out all the photos after the jump…
