Mil-Spec Automotive is known to turn civilian Hummers to monstrous beasts. But the company has worked on trucks as well, especially the Ford F-150. This time, the company again laid its hands on the world’s best-selling truck to give it a twist of its own. The last time the company played around with one, it gave the truck steroids and bumped up the power figures to 500 horses. This time, the Michigan-based company upped the ante and tuned the truck to make 675 ponies! Called the Intrepid F-150 Supertruck, there are a whole lot of other changes that make this Ford F-150 one-of-a-kind.
