I think you'll be opening up a big can of worms if you try to install the powertrain in your truck. The transmission and engine are controlled by the computer that is totally different than the on in the 99. Also, the rear end housing is different because of the shock location and I don't know if it could be modified.

 

I COULD be done. May not be worth the effort.
Do you plan on doing the wiring and welding yourself?
If you have a fabrication shop accomplish the work, you could
easily be looking at $5000-10,000 for the overall fabication costs.

 

Hey guys, your losing me here.

First, if i have the engine harness and computer with the new motor out of the 05, then is'nt it a piece of cake to swap motors ?

Its a 05 4.6 going into a 99 4.6 , how can that be so difficult if alot of other guys are doing the 5.4 upgrade and saying its the bet thing ever. Are you saying the motor mounts and cross member mounts are completely different on the 2005 F150's from the 99's were ?

He told me the rear diff is the same width and only 1 shock mount is on the other side, so i would need to buy a clamp on for the tube and im good.

So far as the 5000-10,000 worth of fabrication to mount a motor and trans, i could build my motor and trans for 5-6K and get 350HP and be a happy clam. But for 1500 bucks, i thought i was way ahead here.

You two make me wonder if i should run out and just buy a 454BBC truck.


9.00am here and feel like a drink already.

 

If you have the harness and PCM then it shouldnt be too hard. I can't see how the motor mounts would be any different...a 99 4.6 and a 2005 4.6 are the same motor as far as I know. You can count on a few bugs to work out but it shouldnt be THAT hard and if you can do most of the work then you wont have that much money in it.



However I wouldnt fool with trying to put the rear end in...there is way to much to change to make it work easily.

 

You would have to completely rewire your truck with the 05 wiring harness. Your 99 guages wouldn't work with the new harness, all your accessories (radio, heater, ac, power windows) would have to be manually plugged in to the new harness, the abs is different, etc. You'd basically have to make one harness out of two.

 

It definitely would not be a "plug-and-play" weekend project. In fact, it would probably end up looking more like Chip Foose on Overhaulin'.......

I'm not sure the economics of the swap would work out, given what you can get a low-mileage used truck for these days......

 

Not to mention the 04+ is fly by wire.

I would just do engine/trans and sell the rear end for 200 bucks.

If you are going through the trouble i would try to find a 3v 5.4 with low miles to swap in. (even tho i like the 4.6's the 3v 5.4 will be a beast in the (much lighter) old body trucks

its not too hard to get it all to work, and yes your gauges would work, but you'd have to do your own wire harness. You can technically put any brand guage on any brand motor if you have the schematics for both.

Even if you could somehow get the powertrain to work, the expense involved would not be worth it. A 99 model two wheel drive pickup is not worth enough money to make it worthwhile.

 

Hey OS, If you were ever to have the chance and see what my 1999 F-150 looks like, "you surely" would'nt have made a IGNORANT statement that a 1999 4x2 is'nt worth the trouble to invest any money into. Especially when my truck was a show piece and is MINT. I guess your 2004 makes you feel real special.

Dont reply either, you'll just show your intelligence level again like the 2 previous posts.


Sorry guys, but its irritating when some answer posts that are focused for technical advise from first hand experience and not from people who just drive a truck.


Thanks to all that are actually helping.

Six posts and already the true colors come out.

Blue book wise a 99 2wd is not worth all that work. If it is special to you then it might be.

If you have a donor vehicle and time time time. It can be done. I forgot where I saw it but there was a web site somewhere out there where someone had done the 3v swap. If I find it I will post it up.

 

To be honest... you should've gotten an engine from '97 to '03 and drop that in there... then it would be ALL plug and play.

The engine, transmission would not work because:

Engine:
- Controlled/connected differently by the PCM
- Drive By Wire
- Less Vacuum Actuated Systems, and more reliance on Servos to do the job.

Transmission:
- Controlled/connected differently by the PCM
- Different communications with the PCM

Rear end:
- Different shock set up... outbound shocks (the '99 has inbound mounted shocks)
- Different leaf spring location.
- Different bolting locations.

 

You ask for help, then you bust my *****?
Come back and ask some more questions when you get some manners Little Man!

What is your technical ability? I've been working on aircraft for 22 years, I have built eight Jeeps, done a good bit of fabrication. The wiring will be the biggest part of it. Transmission crossmember will need fabbed. I would not use "clamp on" shock mounts, I'd weld them and do it correctly.
Contact a shop, get a quote. I stand by my $5000-10,000 quote.

 

^^^ X2, and well-said.

OP - that donor combo is a great deal. What if you - buy it, then flip it or part it out for a significant profit.
Apply those funds against a 5.4 2V drivetrain of the same generation as yours.

 

I changed my mind. I think you should install the power train in your truck and keep us posted. It will be fun to watch your costs and progress. If you ever get it back on the road and you have an accident that totals it, it will be fun to see how you handle the settlement with the insurance company. I handled insurance claims for 30+ years and several times I had claims with people who had high mileage "mint' vehicles who wouldn't accept the true value of their vehicle. Some hired a lawyer (who got 1/3) and sued for what they thought their vehicle was worth. Both sides would go through all their gyrations trying to prove the value of the vehicle and then at the end the judge would almost always ask what the book value of the vehicle was. He would then make his judgement for that amount.
