I am sure this article or question is on here, but I'm not smart enough to fine it. I have the above mentioned vehicle and was wondering if anyone has done a swap into their bronco. Good idea or bad. I am a novice and looking for advice and comments

I have that engine and transmission in my truck. (With aftermarket EFI) It will fit into your Bronco with some modifications.

1) The OEM EFI for those trucks is too tall to fit in the Bronco. You will need a Mustang or Explorer EFI setup which requires a 351 Lightning lower intake OR an aftermarket EFI like FItech.

2) Both the transmission (I'm assuming it's a ZF5) and the engine are larger and benefit from a body lift for clearance to the body.

3) You will need an adapter to mate the ZF5 to the Dana 20 transfer case or you could go big and get an Atlas

4) The ZF5 uses a hydraulic clutch system, which you'll have to graft into the Bronco.


There are plenty of people here that could provide specifics and pictures, as there are several running 351Ws and ZFs in their Broncos.

Performance-wise, the 351W/ZF combo is AWESOME. Tons of torque and wide gears really push a Bronco down the road with ease. I have no issues maintaining interstate speeds. You are only limited by your sanity. Viperwolf and I are running the same cam with different drivetrain combonations, but in both cases, it really woke the 351w up.

I too am running a '95 351W and '89ish ZF. I LOVE the setup. I have GT40 intake and factory EFI controls. It has worked well, and I hope even better after a rebuild and some wiring work!

I have the same combo like above from a 96 f250 sitting in the garage. I'll be doing the factory Efi from the Explorer with the lightening intake. I'm in Erie and if you want to talk shop about the swap, happy to do so. I've got it planned but still working on the body.

I appreciate the input and would love to talk shop. I am not sure when I will be able to start working on mine. I have no place to work on either one of mine. It's killing me. Hopefully I can get a garage built this year so I can get back to what I love. That however has been put on hold because of some health issues (if its not one thing its another). Would love to see some pics of the process or finished product. Sorry about the delay in response, still figuring out how this works.

I was thinking about also switching to EFI.
Pics of everything needed and original part numbers if possible.
