I'm assuming it's an SRT-10 all you will have to ddo if you are importing it for good is change the warning stickers to english/french and add daytime running lamps. I am almost 100% that the speedo has km/h on it so it does not need to be changed.
You are going to have to pay the taxes at the border. Make sure the title is at the border at least 72 hours before crossing or you will be in for a fun surprise. What crossing are you planning on importing the car? Save yourself the headache and use a broker.
