Stick with the 4.6. Too many things to change to swap back to that motor. Bell pattern is different, so you need a trans along with it. Then there is the computer thing, cooling, exhaust, linkages, accessories.
The PCM, harness, the dash issues with Pats etc would be a real challange.
The program the engine is runs on is completely different with camphasing control, drive by wire etc.
In 2004 the program was changes to the OBDII 'can' system.
All new vehichle makes in US marketing had to have this by 2008.
It is a Bosch system design.
Too complex for a casual swap.
Yeah man. I was talkijg about the new 5.0 the coyote. I figured the engine would be similar enough to use the same tranny and motor mounts ect.
I know ford sells the engine and a wiring harness and eec to put in older cars/ trucks. I was just curious if my 4.6 stopped if i could get a crashed f150 with the 5.0 coyote if a swap would be difficult. But it sounds like it would be. My main concern would be working with my tranny. Unless i did a computer, harness and powertrain swap.
If i did decide to do it. When/if thw time comes. I would buy the whole truck. I actually have a friend he just bought a 04 f350 diesel crashed for $2000. Not bad for a running driving truck with a bent frame.
