I want to swap a 1995 351W into my 66 F100. I also want to use a Ford EfI. I have seen in the forums that a EFI from a 1989 F250 would be the best. I cannot find it anymore. Can this be done and what parts of the 89 do I need?

 

You can use the wiring and computer from any year 5.8 truck but ideally it would be from a truck with a 5.8 and a manual or C6 auto, and a '91 or older will have the simplest setup, after that they went from a mechanical to an electronic speedo with a PSOM module that is part of the speed input circuit to the computer.

 

Thanks Conanski. What wiring manual would you suggest for helping with the swap?

 

An authentic Ford service manual would be your best bet.

 

Thanks again.
