Hi I have a 1986 Bronco with a 302 EFI in it but it need a motor i have a donor car a 1989 Ford Grand Marquis with the same engine 302 EFI with this motor work in my bronco without much mods including mounts and wiring harness etc ?........

 

The intakes are different. You'll need to swap out at least the upper intake manifold. The lower one may need to be swapped as well. And I believe you have a different head setup on the Marquis.

 

Ok so if i had a choice i should stick with a truck motor then i want this to be a simple swap as possible ! Also i was thinking about upgrading the motor to a 351W what do you suggest and what years and vehicles would be my best choices ?.........

 

EEC-IV you can use the 351W out of a Ford truck up until about mid 1994. Shortly after that Ford went to thet OBD-II system. The firing order is different, you'll need the ECM module from the donor vehicle. If you are running the AOD, you'll need a different plexplate. I thnk you can search the forums and find out which automobile has the one you need.

When mine started burning oil and became a tired dog, I just yanked it and rebuilt it. A lot simpler.

 

Both upper AND lower intake plenums are different.

Flex plate from a Crown Vic if you run with NWBronco's suggestion.

 

Ok thanks guys for the info ...............
