5.0 efi swap for 5.8 efi - Pirate4x4.Com : 4x4 and Off-Road Forum

I am wondering if it is going to be easy enough to swap. I have a 1987 F-150 with a 302 {very tired}. Would I be able to take a 351 out of a 1987 and it all bolt up and the efi still work? Any help would great!

Yep, you'll need the computer and parts of the wiring harness depending on the computer that is in the 5.8l truck. I just did this swap for a friend. Pretty straightforward if you use all the stuff you can from the donor truck. There might be several differences (probably, Ford changed a lot of little things in production, even during the model year) in vacuumm lines and sensor wires and locations. You just have to trace them out and make sure they are all connected. It took me about 20 hours to do the whole swap including getting some other problems the truck had fixed. I swapped engine, tranny, tcase all at once, though.
Good luck!
