You should do option one. You won't want to wire anything EFI and you have a huge hard on for the modified motors.

The best choice though would be to keep your bronco together and freshen up a 460 with factory efi, put a cam, straight up timing set and shorty headers and put that into your bronco once you have the motor rebuilt. Go to a junkyard on a half off day and stuff as much of the wiring harness as you can in the pan before you take it up front. It will bolt up to your transmission, and you don't have to do any fab work, just bolt in some new motor mounts. There's nothing wrong with speed density, it works. That's why you see all the old mexican workers driving old Ford trucks.

Hi, I'm Karl, with a "K". **** that guy Carl.

There was something bad wrong with my speed density 302, I'll give you that, but my junk yard roller motor 351 that was speed density ran like a scalded ass ape. Frick has told mehis350 tbi didn't have the ass that 351 did. On several runs people came up to me and said, "Man your big block sure does put some power out"

My advice, and it's just my advice, **** the 460' it's heavy, you have a doubler, you are making a crawler, not a mud bogger. The only legit reason for a big block in the Offroad world is a mud bogger.

Find a good running f150 or f250 with a 351 (**** a 302), part the truck out, keep the motor/trans. Trim the harness. Rock out with your cock out.


The acc. You are trying to save are an alternator (150 tops) and a power steering pump (150 tops).

Above all else, do not try to adapt fuel injection to a carb 460, that is just dumb for a rock crawler.

Again, my opinion.

Side note, any engine with a 2 barrel motor craft carb, I support.

I kinda support the 351 idea, but it cost more to make the power a 460 would and I don't think tommy would be happy.

IIRC the 460 is only a couple hundred pounds more than a 400, and I don't really see this as a dedicated "rock crawler."

Find a running fuel injected 460. Then swap into your truck and run it until you can build a new badass 460. After which you will have a 79 bronco that kind of fits down trails, makes lots of hp and noise, and you will be able to show off anywhere from Alto to Clayton... Until you have a catastrophic break down ( which we all know is another form of showing off ).

can you get overdrive with the 460?

Yes

E4od has it

He has a doubler, if he wants to crawl he does not need displacement. If you want to mud bug go get a big block

460 with 2 motorcraft 2100s and a big cam with a bunch of lobe separation.

I never caught why you are throwing out your old motor. Blow it up? Anywho, I would rebuild the 400 that is in it and put a big cam and high flowing heads, or if it has already had that done to it take the next step and stroke it.

Tommy's motor runs but smokes real bad on throttle. The only good thing is you will never get west nile virus riding in his bronco. If you're spending all that money on a 400, why not spend it on a 351 or 460? The whole point of suggesting a different motor is so he can use factory EFI. It doesn't need a bunch of power anyways, it just needs to sound good. Big cam with lots of lobe separation, that way every redneck at alto asks if it's got a cam in it.

Perhaps an RV cam? :D

Too smooth

Doesn't matter what we think Tommy will do what he wants. I suspect he goes with a 460 and a cam that doesn't idle very well with some carbs.

If it were me I would swap an LQ4 or LQ9 in place, if you wanted to keep with the Ford find a 5.0 Coyote

Tommy if you do go factory efi 460, do some research on cams before you buy anything because if you change the efficiency of the motor then the speed density computer won't calculate the mass of the air right and it will run like dog ****. That's where mass air has the advantage. Speed density motors do really well with boost though.

Just go all out and throw a 6bt in it.

Then I'd have to get tow mirrors......that defeats the point of narrowing it.

Glad to see you're thinking clearly :gigem:

scrap the whole thing and throw an LS based something or other at it. Always the answer.

Preferably.

Good luck Tommy! Just keep that big bitch running.

I was going to look but this thread is 48 friggin pages long. What the ****. At some point I seem to remember you being very attached to this motor because you had sunk a lot of money into rebuilding it. No? Also, DavidO has a good post on the first page :)

its blown.......why would I keep running it? There would be no mosquitoes left in the world, then all of the frogs would die and we couldn't gig them....

Welp, Flywheel finally got to the point where it won't start anymore while chet was doing some a-1 towing recovery. So I guess the motor rebuild is going on an accelerated timeline because he has to pull the motor to replace it.

Why do you have to pull the motor to replace the flywheel?

He doesn't like pulling the tranny

Never know what you are going to get when you give a tranny a tug...

two birds with one stone....

I have a 460 with a big cam that could be bought. Only been on about ten trips since rebuild.

pm me a price

I wasn't gonna go 460, but if it's big nasty's 460 I guess I have to. It's destiny.

Better plan on hydroboost brakes.

It would be a good idea anyways on the bronco

Do it

That's way overpriced. I bought a non wrecked truck for not much more. If you put a 7.3 in, put an obs motor in it. Also plan on hydroboost brakes.

And it's debatable as to which one is in better shape!

Not anymore

Fixed it for you.:flipoff2:

More than that. Tranny and injectors alone go over that. But I'm almost done being broke because of my truck.

Are you going to sell it?

No, I'm just done fixing all the broken and worn out parts. Only things left are a new steering box and lock outs.
