Good evening!
It looks like 430,000 miles is finally enough for my little 302. Time for a heart transplant. Anyway, she's my 1986 Bronco 302FI 4 speed (no OD)
What's my best course of action? I've always wanted a manual 351 Bronco because they were never built in my style. However, I'm not willing to give up FI, and I'm colorblind so rewiring the PCM isn't an option. Are there any plug and play 351s, or am I stuck to a 302?

Thanks in advance!

There is no difference in the wiring between a 5.8 and 5.0 of this vintage so you just need a complete 5.8EFI motor from an '87-91 truck with the matching PCM, and with a 28oz flywheel the motor will bolt right in there.

 

Would I need to change anything else? Fuel pump, radiator, etc?

 

Nope that is all the same.

 

Conanski, i thought the 85-86 efi was wired up differently then the 87-91 models. If you can locate a pinout schematic just to be sure. otherwise what he said will work.

 

OK... yes those early EFI trucks were put together a little different than the later trucks, but that doesn't matter because any wiring that comes with the donor motor must be removed and discarded. All the sensor and devices on the motor are the same though so the original 5.0 harness will plug into the newer motor.
