Here's what we know.
Ford is treating the streets of Detroit to sights of a prototype GT and witnesses claim that the engine is not the production twin-turbo 3.5L EcoBoost V-6.
With new EPA approved exhaust, a new engine appears to be certain and Ford Authority says the 7.3L Godzilla V-8 will fit in the GT's engine bay.
If Ford is truly coming out with a Godzilla-powered GT, it better hurry as GT production is scheduled to end in less than two years.
