ok so i want to add more power and mainly torque to my truck, eventually i'm going to go F/I but for now just looking for some bolt on peices (such as a bored TB) what items are out there for the 4.7l? i'd like to give the engine a good cam but i'm honestly not sure what that takes to do. i'm looking for little weekend projects, nothing that will require alot of motor work.

The best would be to get some HO cams (currently on national back order) 08 intake manifold and a larger TB to start

the 08 intake mani will fit the 03?

yep, but you'll need to but the adapters that Air_Ram sells to make your TB fit on it

If you decide to get a new cam.... get 2.... you'll understand why.

to explain, the 4.7 is an overhead cam motor. You have one under each valve cover

ok care to explain the cam thing. and why not just grab an 08 TB and port it as well?

ah yeah i was gonna check on that. what does that do.. sorry for the noob question.. don't know alot about engine building.. i mean i can replace any part.. but i don't know much about the specifics of things. it changes the timing a little bit right

the 08+ TB are a cableless TB controlled by the computer

oh that makes sense

it changes the amount of time the valves stay open and close and when they open and close

One cam per head:
