Welcome to the site. Deer are such a pain. I just bumped a couple of does at less than 5 mph and busted the pass side headlight, grille, turn sig and both headlight housings!!! I do not think the swap would be too much trouble, I would go with the 6.0 You will need the PCM and wireing harness for it. Where in KY are ya? I'm in Northern Mid TN.
