Nitrous Oxide is a chemical supercharger .
The whole idea with a blower/turbo or nitrous is to get more air into the engine.
All 3 basically accomplish the same thing
Nitrous might be an option for you to check into,alot cheaper then a turbo or supercharger
The 4.7s are known for blowing head gaskets and warping heads because they're aluminum. I've had it happen twice to me in my '04 quadcab. I was considering putting a turbo on mine, but a mechanic that specializes in Dodges told me I would end up burning up my new engine if I put one on it. He said they are easy to run hot and from my experience, he's probably right.
I would go that far if you get it hot it will blow a hg though I have blown 2 both in a way were my fault the first didn't have the cap on tight after a check and got caught in traffic the second my efan blew a fuse once again I was in Houston rush hour traffic where I could really get out. I have a turbo in the works now the biggest concern is the pistons and the top ring only being an 1/8 of an inch from the top. I have owned my turck longer than most I've had it since 05 and changed just about everything on it.
