I currently have a 2013 challenger 6 speed RT. I have a 2006 5.7 engine that came out of a durango and wanted to know if I could build this and have everything still mach up when I install it, all accessories. I would use the newer eagle heads as they should bolt on. I know the current engine is a VVT motor and the 06 is not and think that could be fixed with a tune or PCM change. from what I see there are a lot more cams to choose from with non VVT engine and I could build this over a year or so and still have the car to drive now. any feed back would be greatly appreciated.
