5.0/5.8 efi swap in early bronco

I have a 1974 bronco. I'd like to put a fuel injected 5.0 or 5.8. From what I've read 1989-1993 are the years to get the doner motor from. My next question is what ford vehicle are the best to get it from. I've found an 1989 crown vic with a 5.0. Is that the same as the mustang 5.0? What about the truck/van motors? I understand that the intake needs to be swapped for the truck 5.8 to fit in the bronco. What about the truck 5.0 intake? All advice is appreciated.

It'll work, but it's probably not the same engine as a 5.0 mustang. The 5.0 HO got a different firing order and cam. It uses the same firing order as a 351. The basic 5.0 EFI (which is probably in the crown vic) used the standard 302 firing order. If you use the 5.0 from the crown vic you have to use the same EEC. I'd use the 5.8 and do what ever you have to do to make the intake clear. It's a stronger block and can handle more horse power (can be bored/stroked to 428+ inches).

Yeah. i'm definately leaning towards the 351. The crown vic I came across is almost free. I think I should snatch it up for the efi parts if they work on the 351?

Send a message via ICQ to Bigtoy22
if you go 5.0 get one from an explorer. they used the gt40 heads and intake stuff,, heads flow much better than the mustang units.

I would suggest that if you get a truck 351 to get one from a 90 up. I know the 88 and 89 used a exhaust gas recerculation directly into the head. It sucks and takes up a bunch of room then burns you when you have to work on something.

Wouldnt that be an EGR system? Why would the 90 and up not have it?

Have you checked out www.fordfuelinjection.com? That will answer a lot of your questions. Check the magazine articles on that page in the right column.

They all have an egr system but those years they tried pumping the exhaust gas directly into the head. I can't tell you why they did it I have just had to do a few engine swaps on those years and the 302, 351, and 300 all have that crap on 88 and 89 not sure about 87 but 90 doesn't have it. All it amounts to is several hot pipes in your way when you have to work on it.

Also the mid to late 90's 5.8's were roller which is a plus, then just do 89-93 mustang harness and computer, motorsports 5.8 efi lower and xplorer/gt40 upper and 24lb injectors. It'll work great.

Thanks a lot guys. The search is on. She's in for paint right now. I'll post progress pics. I've decided on a 92 and up roller 5.8 out of a truck, gt-40 intake from the explorer and mustand computer, with BC broncos wiring harness. Looks to be an easy swap. That's based on my chev install in my pro rock crawler... I've heard the ford stuff is a pain in the ass. Luckily it seams to be a pretty popular swap. There's no shortage of bolt on parts for sale out there.
