Bronco Info: '89 XLT SAS ~'78 Ranger, '88 F350
Crazed 460/ZF swap

Gonna get both rigs in the driveway and start taking them apart tomorrow.

You should know the "Street Truck", it is my '89 XLT, It started life as a 5.0/aod



I did a 6" superlift TTB lift



Did a 351 swap, mass air



D44 SAS



9" rear




I have never been happy with the 351/aod, I get crap mileage, and It was just time for a change for me.


I picked up this truck



It has a 460 EFI and a ZF 5 speed.




I will post lots of pics as I go along, I wont be spending too much on the swap, I will upgrade things later on as needed.

I am gonna put the mass air on the shelf for now and run the stock 250 computer and harness.

I got the trucks up into the driveway




Put my 33s on the front, every little bit helps on these lifted trucks

I have been wanting to do this to my 95 since I got it.
I have always been a day late and a dollar short when I find donor trucks.

Any plans for the motor while its out? I know there are limitations with the SD system on the 460's just like on the 351's. But if I remember right, there are better cams that will work with Speed density.

I wanted to do this to my 93 but my parts truck ended up being in better shape than my bronco so I sold the bronco .

Good luck with the swap, are you going to replace anything while the motor is out? oil pump/freeze plugs/timing chain are def a good idea if nothing else, very easy to do while motor is out. You wouldn't believe the slack in the timing chains I've replaced, both the 91 and the 89 looked ready to skip a tooth they were so stretched.

ROTFLMAO. If you think your fuel economy is bad with the 351, just wait until you have to fill up "the fridge" for the 460--ZF or not.

Either way, I take my hat off to you for your drive and determination. It sounds like a sweet combo, and I'm envious.

Take your time on that engine, and build it like you would if cost were no object. You've got a DD. May as well try to get 600+ LBs per FT of TQ out of that monster. Clearly, the rest of your truck can handle it.

Good luck, and thanks for sharing.

Can't wait to see how it turns out. Like many others, I would love a 460 in my bronco as well. In 2004, I had a carbed 460, but went with the 302. EFI 460 is the way I'd like to go now. I only drove my bronco 1,300 miles this last year. I put it away in the winter and it's not a daily driver, so low mpg isn't a huge factor. Good luck. Buying a complete donor truck is the way I'd go as well.

Huh..

That's odd.

I'm stoked with mine, waaaayyyy more power than the 302 and I am getting 12mpg city.

Well I'm sure it will be a top notch swap, as always.

Are you going to do anything to the 460, or just do a straight swap?

Also, I wish I had your funding

Wow you get 12?

after the 351 swap i got 9, did mass air, it dropped to 8, and has progressively got worse till the last year or so it has been in the 6s.

I will do an oil pump, and a timing chain, and I'll clean it up, but for now this swap will be all stock.

Wish I could tell you what it might have been, but all I can say for sure is
something was wrong with your rig. :/

My junky '91 Bronco I bought abandoned for $700 then threw back
together, swapping parts all over the place, also gets ~12.3 mpg -mixed-.

351w/125k then added a ZF/188k and a '90 F250 EEC... but I did keep up
with my speedometer gearing and/or calculate in the odometer error when
figuring mileage tho...

http://www.panix.com/~alvinj/file12/SpeedTable.jpg

Could your low mileage been this simple? ...were you going to progressively
bigger tires and not figuring in the reduced odometer reading? {shrug}

nope, I have 4.56 gears which works out pretty close with the 37" tires.

Overall I did too many engine things at the same time to be able to pinpoint what went wrong.

The 351 will find new life as a carbed replacement for the 302 in my 64 Fairlane.

If some of those fancy 351 parts start collecting too much dust you could always sell them. It just so happens that I am in the market for some of that stuff. PM me if you do decide to get rid of it. On a side note, that is one nice truck. I also have a 1988 f250 with the zf and a 460 with 4.10 gears, it got 10 mpg anywhere, didn't matter if it is loaded or not.
