Want to know if an 03 f150 engine will wire up and install right into my 97 f150??

 

yes, but there is one difference and i cant remember it off the top of my head. And i thought yours was a 4.6...

 

Nah I wish. . . I got the baby 4.2, do love that engine though

 

Pats might be an issue.

 

I think if you use the intake system from your current 4.2, you should be fine.

 

PATS is not an issue.

 

I installed an '04 4.2 in my '97. You need to keep your plenum & fuel rail, also keep all of your sensors. There is an issue with the knock sensor, but you don't really need it anyway. I zip-tied mine off to the side, & left it there. Truck has been running with no problems for over a year now. Some of the brackets up front will have to be changed also. No big deal.
