Default 07 to 04 5.4 motor swap

I'm thinking about purchasing an 04 extended cab parts truck for my 08 super crew f150. Anyone know if the motor and Trans will line up without issues?

Should be a direct fit except for the drive shaft and if you have 4WD.

I'll be in this boat here soon. Closing a deal on a lariat supercrew 2004. Needs a motor. Right now I'm researching if the trannys are the same. I know I'm 2006+ they used the 4R75E and 2004-2005 used 4R75W

Id try and find an 08 truck. You're going back to the old plug design and the most problematic phaser era...But yes, it will fit fine.

Also would anyone know if the expedition used the same motor and tranny? All the f150 in Pittsburgh have been stripped

Depends on the builder. Some will use the 08+ heads requiring use of the newer designed plug. Good question to ask the company you're considering buying from.

Reman motors will use same plugs as all other 5.4 3v.. sp515 or autolite HT0 plug.. The boots on the coils were the only change.
A reman will come with everything you need except the valve covers. 07-09 valve covers have fixed vct seals were 04-06 have removable seals for easier vct solenoid maintenance.
Oil pan on 04 model only includes a oil temp sensor in the pan.
You will need to reuse your intake manifold, and valve covers.. All driveline accessories including your water pump, AC, alternator etc will need to be reused or replaced..
What I recommend for "easier to replace it while your at it parts is.."OEM or better"
New flexplate and bolts
New starter
Oil dipstick
Water pump
Short tube headers (stainless)
All pulley bearings..
^^^ this will ensure nearly zero post install issues^^^

This project could turn into a nightmare. The owner who has a garage, already pulled the motor, and completely tor it down. I mean when he took me to the engine. I saw a block, leaning against the wall, with heads and cams next to it. On the other side of the garage was the accessories and "everything else". The owner seems really helpful and said if I need help with anything he wouldn't leave me hanging. But I was trying to buy a whole doner truck and see how the stuff came apart. As I've learned before. If I didn't take it out, it could be a challenge to put back in

Incorrect. The heads on the late 07 and 08 models had the heads completely redesigned to accept a standard plug. I have seen some Ford remans with the newer design. It really depends on what heads the core had on it when it was rebuilt. My 08 uses the MC SP-509 plug.
