Will a 2012 dodge charger rt 5 7l v8 engine motor hemi chrysler vvt 370-hp OEM 12 fit in 2006 durango?

No, a 2012 Dodge Charger RT's 5.7L Hemi won't fit directly into a 2006 Durango without significant modifications, likely too extensive to be practical. While both vehicles are Chrysler products and use Hemi engines, the engine bay, mounting points, and ancillary systems (like wiring harnesses, exhaust, and cooling) are different enough to create major compatibility issues. It would require custom fabrication and a massive amount of work to make it fit.
