V8 Swap - many questions

Hi, My name's David. I'm new to BII4x4.com, and i think this place is awesome! First thing, i want to say, i know i can search for this information, and much of it has probably been covered to death... But my only internet access is my ancient computer ( :mad2: ) with a... Wait for it... 14.4k modem! :wtf: so searching is nearly IMPOSSIBLE! :hmmm: ...Anyway, i have a laundry list of questions and details i need to clarify, if anyone would be willing. I know specifics help so i will try to be detailed, and organized.

To start off, let me tell about what i have.
1990 Ford Bronco II XL 4x4
Stock 2.9V6 (165,000 orig miles)
Stock tran/trans case
Stock.. :idea:
Hell, everything is absolutley stock except for the 215's and my head-unit.

I plan on doing a full v-8 swap, obviously. My application is 1/3 Daily Driver, 2/3 Mud Toy untill i can fix up my '94 Mustang for a DD. Not full DD, but i need it to be driveable on the road a decent amount - Yet i need it to be able to take quite a bit of beating offroad. And i want to push, at minimum 31's, but probably 33's soon, 35's max.

To make the swap easier, i already have a 3" body lift i need to put on. I cant fab for crap :no:

My budget... Sucks :hmmm: Bout $$700-900 a month, if im lucky - for the time being, School appearently has to come first... :redneck:

Anyway, to the questions.

I know the 91-94 sploder are very good for having mostly everything, but it never hurts to have options, right?

Engine
I preferably would like a fuel injected 289, but a carbed 302 is starting to sound much more appealing.
-preferrably mass air flow censor, if applicable
-Which model/years can i find a suitable 302/289
-Any difficulties or trouble areas in the engine area during swap
-Anything worth note needing to be changes/removed while possible
-Any other specific info or insights or tips are most definitly welcome.

Transmission/Transfer Case
-Preferrably manual if it affects later information
-What model/years are good choices
-What is a good tran/t-case combo for my type of application
-What model/year for t-case
-Preferably no notching in the frame (very little fab skills, but i have to learn sometime)

Front End/Rear End
I know sploder 35's and 8.8's work, but should i look for any other front/rear's? Im also confused about the TTB front end thing (what is it?) - because i've heard it has some bad downfalls, thus why i wonder if i need to look for anything else, or keep it TTB, or even leave them alone? Probably having to change both, it would be nice to get disc rear.
-which model/year for front/rear, respectivley
-would the ABS system be messed up, or complicated if i went to disc rear?

Suspension
I plan on getting cut-out fender flares, and cutting quite a bit to make it easier to stick 31's/33's.
-should i get a suspension lift, if so, how high, and from where would you reccomend.
-if i change the front/rear ends, should i try to go leaf spring, or coil springs, or any specific combination?
-Is there anything i need/can do to compensate for the added weight of the new engine?

Mods
I know mods are mostly depending on personal style, but...
-Any performance add/bolt ons i should add for a little more torque to get my wheels turning? Of course, depending on if the axle set-up anyone reccomends would need more help to turn the wheels

Exhaust ?
I doubt it, but is there any chance that some ford model comes stock with a dual exhaust that i could grab to fit my application, with some fabbing/moding? I would just rather not spend $7-800 on a pro dual exhaust. No biggie, just curious

Mounts, Hardware, Fans, ETC
Economy to middle of the road perfomance being kept in mind...
-motor mounts?
-Hardware Reccomendations?
-any fan reccomendations? a cool engine is always a good thing
-Brackets, what have you, or anything else needed/reccomended?


Well, i think that should just about cover it. Im sorry its so long... I hope no one wants to kill me... But like i said, im lucky i can even go online - im that far out in the boondocks - the smiley selection alone took 15 minutes to load...

If anyone feels like it, i have a small block ford V8 from a 77 f250... how bad would that be to try to stick in my B2? Wont do it, but it just came to mind... Probably going to turn that F250 into my mud club's Vehicular Rescue/Removal vehicle anyway.

Again, thank you all so much, i really appreciate it!!! [/b]

first off if you have never done motor swaps before and you plan on driving this thing on the road I would not try a motor swap right off.

if you are only wanting to run 31's the body lift will get you there.

I found this topis on the first page dealing with a 5.0L swap:
http://forum.broncoii4x4.com/viewtopic.php?t=1709

that topic also talkes about transmission options.

I know you have slow internet but you realy need to do some searching before you do any of these upgrades.

I always try to tell people when you get a new rig to play with it first and find the stuff that will help you the most. to jump straight into swaps and up grades with out knowing what type of wheeler you are or how far you realy want to go is not a good idea. my advice would be to install the body lift and 31's. then drive it and wheel it for at least 6mo. then look at the next step. I can tell you that driving off road is mostly the driver. you can throw money at a truck all day long but if you can't drive you are realy not going that far. I can take my stock ZJ most places people wouldn't dream of trying to go...

I will echo what D says, throwing money into a swap can be one the most frustrating things you'll ever regret, and never forget.
I wheeled my BroncoII as a stock vehicle with only a welded rear for a year before I decided to swap axles(something that will be needed nearly immediately with a V8). I did a 44sas and a 9" rear, left everything else stock. I did have a fairly fresh crate engine that only had 14k miles but the tranny and Tcase had OVER 300K miles on them, and performed great. I did recently do a 4.0 swap and automatic tranny, it wasn't a necessity thing, just one presented itself to me for under 400.00 complete.
Do what D says and wheel it for 6 months or so, and then decide if you really need a V8 or whether it was just the "in thing" to have.
