96 Bronco Drivetrain swap
I don't really want any reasoning as to why I SHOULD NOT do this. I would really like some advice from you guys on how difficult it WOULD BE to do this considering I have the parts at my disposale.
Idea 1: Changing the EFI 351W to a carbed 351W. From my understanding it is very easy to go to carbed from EFI (not the other way around though) and I would have to change the trans because it would no longer be shifted by the computer. The thought of this would be to avoid a dyno to adjust the computer when i build a 393 stroker.
Idea 2: Swap the entire drivetrain in the truck with a 79' Bronco's Drivetrain. (Engine, Trans, Transfercase, and axle.) I would probably go with a 460, beacause I can
Put a C6 trans in and a np205 transfer case. Then put in a Ford 9" in the rear with Posy 4.10s and a D44 in the front off a f350 of the year (so I have leaf springs) with posy 4.10s in it.
Idea 2 1/2: Would a newer Ex's axles (like 2002-2005) work with a 79 Bronco's driveshafts? (So then I have leafs front and rear with D44 front and D60 rear.)
Just so crazy Idea's me and some friends got last night and I was wondering how difficult they would be. Thanks y'all.

Well anything is possible, however, lets get a few things out in the open.
Going from EFI to Carb is a terrible idea. If you do decide to do this though, I'd gladly buy you EFI parts. (working on converting the 68 Mustang to EFI) Carbs are picky, requiring constant tuning to be driven year-round at peak performance. You will lose MPGs (not that we had much to start with)
The 460 and C6 would work no real issues there.
The 9 inch really isnt that much better then the 8.8" If you plan on giant tires then I'd nab the rear Dana 60 when you're looking for the front as well.
The SAS (solid axle swaps) are very common, there are tons of threads on this if you search.
I have seen a few threads where people have used the newer Excursion axles and even the 08+ Super Duty axles. If you can weld or have a large bank account, either one is possible with some time.
You are right in saying that if you swapped to a carb that the tran would not operate properly. The E4OD is all electronic and at best is finicky, even with the EFI in place. You would need to swap in an older C4/6 or a manual trans as mentioned.
Hopefully my ramblings here help point you in the right direction.

Why don't you just sell the 96 and buy a 78-79 since that is essentially what you want?
Why pick apart a functioning 96 just to take it backwards 30 years in technology?
I mean, its your money and your truck but everything you are talking about doing is basically a stock item in a 78-79 unit! What is left in the 96 after you do all that that the 78-79 doesn't have?
Lets break it down:
Idea 1: Changing the EFI 351W to a carbed 351W.
78-79 models already have a carburated 351 (minimum)... no mods necessary.
Idea 2: Swap the entire drivetrain in the truck with a 79' Bronco's Drivetrain.
78-79's already have their OEM drivetrain including a transmission that will accept a 460 WITHOUT modification... no mods necessary.
Idea 2 1/2: Would a newer Ex's axles (like 2002-2005) work with a 79 Bronco's driveshafts? (So then I have leafs front and rear with D44 front and D60 rear.)
No Bronco EVER made EVER had leaves up front and doing so is counter-intutitve to suspension articulation not to mention the coils are just a better option all around... AND... 78-79's already have a solid D44 up front and you won't need to spend countless hours fabricating suspension and spring mounts to a frame that was never designed to have them where you need to put them. Expedition axles? Seriously, the other end of the quality spectrum from the 9" you already mentioned!
I hesitate to be any more obvious about my thoughts on this project lest I begin to sound antagonistic, so I will say this again, its your truck, your money, and your headache. Best of luck whatever you decide. Keep us posted. It'll be worth the chuckles.

1) my buddy owns a machine shop so fabrication won't be hard at all.
2) I said excursion axles not expedition axles.
3) my truck had been up for sale for almost a year now and all the people that call me... Are tire kickers.
4) the reason I brought up going carb is because I have been told countless times that I would have to dyno the truck if I go with the efi stroker I want which is another $1000.
5) a friend if mine told me he'd rather have leafs up front on his 79 cuz of the weight of the engine/plow..
I was just pitching around ideas to get opinions and clearly it wasn't the smartest of ideas cuz now I look like an idiot..

Don't be too hard on yourself. I think we've all had some crazy ideas at one time.
The frame on the 96 is alot more difficult to install leaf spring shackles on then the older frames. So that is working against you.
The excursion axles are very expensive and not to mention suspension requires precise welds in order to function safely.
If you want to stroke ANY of these old pushrod motors and build power carb or not, its going to have to have a Dyno tune to be done correctly. You can't just think throwing a bigger motor in is going to solve your problems. I think if you look at the numbers the EFI 351w is putting out more then an old carbed 460.

The efi 351w does put out more stock power then a carb 460 but there is no computer to be readjusted which is while theory behind going carb to put that out of the equation.

If you have a mass air set up then you can tune easily.
You might check out the lightning forum at nloc.com before doing any drastic engine changes. There are guys running stroked 408's and still have efi.

A fuel injected 460 would be awesome, but not exactly cost effective for him as he already has an EFI 351w, he'd have to find a EFI 460 (not too many) and the trans to make it work.
The point still stands, that no matter the motor, a properly tuned EFI motor will make more power then a similiar carbed motor, and be more reliable.
You mentioned money was tight, I would not begin a stroker build until you have set a good chunk aside, they are not put together properly on the cheap.
