I have a 2003 f150 4.6. If I decide to replace the engine, will a 5.4 bolt up and plug in without any problems.

 

There are many threads on this forum about this swap

 

How many threads do we need about this truck? Engine swap, tuner, intake.... PLEASE, for the love of all that is holy, make ONE thread and ask all of your questions about this.

You won't win many friends or get many answers how you've spread your seeds.
