I have a 6.6 engine in it that I am wanting to put new heads, cam, intake on to try to give this gutless beast at least a little bit of power. Does anyone have any recommendations on what a good combination of the three would be as well as anything else that would need to be done to it? Im pretty new to this stuff and im not sure how you would go about matching things up. any help or suggestions would be greatly appreciated. thanks in advance.
