Ok, so I have my Ford 302 from a 1990 Bronco and It has Fuel Injection. I know they make aftermarket manifolds for my engine but I've been offered a stock intake manifold and Carborator for free off an older 302. My question is does anyone know if a maniflod and Carborator from an older 302 will swap in on my engine?
 
I had a 302 from a 1970's truck and as far as I know people were converting the 302's with a licoln town car. I think it's the same but check google for bronco sites I can't remember the name of the site but it's a bronco only site and it has alot of info on that conversion. I doubt you will find muck info on EFI to CARB because most people want to go the opposite way. I know the older engines had to have more holes tapped for extra bolts in the newer manifold but I don't think you would have to. If it's free I would get it and try. With the route you want to go and having experience with a CARB I'd try to wait and make sure it stays EFI. You will have some money into the setup with a CARB especially if you aren't very experienced with it. If you plan on rock crawling it would be a better choice to stay EFI as well. I know plenty of people have no trouble with the CARB but they also have alot into the setup. If you run a CARB most likely you'll have problem on inclines whrn the front is pointed down. The engine will try to bogg. The reaction time will be slower and gas milage will be worse. Hopefully my .02 helped.
 
Yea I know carbs are pretty limited on angles they can handle and stuff, but yea since it was offered to me I figured i'd at least use it to get the engine running. Besides, setting up a custom feul injection system is waaaay past me, plus I priced the efi kits they make and it is ridiculously expensive to go to efi, so for now i just want to get the ngine running. Later on down the road i was planning on getting a Truck Avenger Carb, thasts supposed to be able to withstand angles at least a little better.
 
Ricky, read the propane section. Pane would simplify your engine and increase your wheelability, and it's so simple, and not too hard to install
 
Ok, I just read it, here's two questions:

Can you modify the engine and not mess it up with propane (whatever heads, cam, nitrous, blower, stroker kit, etc..) because I definitly want to do some type of hp upgrade later on down the road.

Also does the engine still sound like its a gas powered V8? I gotta have a loud rumbly engine.
 
You've got EFI on the engine now, you don't need any custom programming... Unless, of course, you didn't grab everything off the donor engine.

Anyway, you've GOT a daily driver and light duty wheeling rig already... take your time, and do it right, the *first* time... What's the rush?
 
I'd find a local junkyard and get the top half of the engine and a computer. You can probably find the whole engine and comp for a decent price. If someone is willing to give you something normally it's because it isn't working. It will probably help with space as well.
 
Aight so here's what exactly what the engine is: a 1990 302 Ford Bronco Fuel Injected engine. Now I found that I can get the throttle body for it if i want the guy has it at home, but he doesnt have the wiring harness. If persay i was to get another wiring harness off a 1990 ford bronco 302, how in the heck would i wire that thing up? From my limited knowledge of wiring, the computer ties in not only to the engine but the rest of the vehicles electronics does it not? How would I get it to just run the motor?
 
www.fordfuelinjection.com Ryan can get you a stand alone harness that will work with ANYTHING

Yes it usually ties in to a tranny shift module but from a 90 (aod) it may/may not. Mine 94 302/E40d did but I fooled it by bypassing the safety/neutral switch to give it a "ok to start" signal.

Saf T can you verify the 90 info, if it controls tranny shift or not?

Thanks for the link, do you have any idea off the top off your head how much a harness like that would cost?

Yeah, but you don't need it.

Just get an OEM engine harness and an OEM chassis harness from the engine connectors to the computer. Cut out the unnecessary stuff, splice in ground, +12v continuous, key on +12v, etc.

If it were me, I'd hunt around for a car intake and harness (or Explorer, but $$$), or put a carb on it. Plenty of good tech around for getting a carb to run halfway decent on the trail.

What transmission would you use? If manual, you'd need to figure out how to get a VSS signal to the computer, too. Lots of little driveability/stalling issues with no speed input to the computer.
 
We'll just have to find out, actually no :( , but im hoping i can teach myself as I go plus my best friend thats helping me build this thing is currently attending nascar tech so he's a big help. But basically it's two 19 year old guys tryin to learn as we go.

As far as transmission I want to run the ford AOD. btw saf-t, how the heck would I know which wires are which (unesseasry wires you mentioned)? I'd personally rather having a custom one made that I can just hook up and go.
 
i wouldnt run an AOD, id run a C6. all 302 bronco's since 86 have throttle bodies, not true EFI. leave that and dont worry about the carb. not worth the extra time, money, and effort to convert it.

Go to the library and check out the Haynes or Chiltons for the car that you got your harness from. (Or better yet, the Probst Ford EFI book) Flip to the page with the engine harness schematic, and start labeling wires. Most all of the ones on the engine side will just plug in, but on the chassis side, you'll have to sort them out a bit. It only requires about 6 connections to the new vehicle once you get the garbage cut out.

A custom harness will probably be worth more than your entire project.

Edit: And best of all, when your EFI up-and-quits on the trail (and it WILL), then you'll be intimately familiar with all the pieces and parts so that you can repair it... rather than having to call Ryan McCormick to find out which wires went where, and where you need to check for voltage, etc etc etc.

Ok, your probably right on the custom harness being expensive, so I guess I'll start looking for a complete wiring harness with computer out of a 1990 ford bronco that had a 302.
 
Do you know if the truck gooseneck intake will fit in your Sammy?

That's why I suggested a car intake.

I dont know if it will or not, but i got that whole assembly now, so if i see its a problem later on when i get to dropping the motor in I'll figure it out. The samurai does have a 3" body lift on it so hopefully that will help in the clearnce department. Speaking of clearance, I still dont know what im gonna do about a fitting a fullsize radiator :confused: .
