Other than the fact that it is at least from the 70s, the thing that made me think it could be real is the multiple competition preped 427s that were in the shop it came from. The machinist had a lot of high end engines that your average machine shop will never see because you have to have a great rep to get business from guys with tunnel port and high riser 427s and 426 hemi builds. He had a lot of serious hardware in his shop so the cobra carb box really wasnt out of place.
