I did a search and did not really find any info. Basicly wondering if I could use a 04+ 4.2 in my 97 f150. I figure I would have to swap over the intake manifolds since it appears the newer trucks were drive by wire. Any info would be great since I can find 04+ much cheaper than 97-03 motors. Thanks!!

 

The block is the same, but the electronic part is whats going to screw you over. If your 97 needs an engine, I would personally look for a 4.6L V8. They are a lot more common than the sixes

 

wouldnt I need a new ecu/wiring/etc to swap in a 4.6?

 

ima take a stab in the dark and say , youd prolly need to completely rewire your truck along with a new computer yada yada yada.. but if you were just wondering on using the short block then im almost certain they are the same ..

 

the 97-98 trucks were very basic. in 99 Ford intoduced the PATS system in which almost everything was computer controlled. the ECU from 99-08 is no way compatible with a 97-98 truck.

 

well it looks like my 4.2 has a dead cylinder so i am just going to find a used 4.2 in a recycle center. will the 4.2 econoline v6s from 97-03 work as well?

 

yes

 

awesome i found a 4.2 out of an 02 econoline with low mileage that i am going to try and pick up on friday!
