Don't waist your time with a factory 4.6 cam, you won't really see any difference.
There are good aftermarket cams that can make some great low end torques and power. If you can't find them, talk to Tony at LRR forum, he is the owner and also has a great repair shop. They install cams in quite often, You will need new lifters, timing chain and gears, upper gasket set plus hoses and all the fun little parts that broken along the way. Depending on your mileage, check out the rocker assembly for wear while you are in there. Before you start, consider doing a really good engine flush to get rid of as much crap as you can before opening it uo.
And yes, it can be done in the truck and is pretty straight forward.
