In the process of deciding which engine to install in my Bronco (78), and so far the choice is between a 400 or a 460. The main hitch to my decision is my desire to use EEC-IV engine management system, and therin lies my question. Did the 335 series ever come from the factory with fuel injection? If so, what engine, and what is the relative scaricity of the intake manifold?

I was all set to install a later model 460 in the beast, but after reading more about the 400, this engine seems like the perfect choice to replace the 351M that resides in it now. The major sticking point in the conversion is the lack of FI, I don't want to take a step backwards and install a carb on the truck. I realise I could install a Holley Projection system on it, but have not been impressed with that system as a whole.

Any assistance will be much appreciated.

[updated:LAST EDITED ON 15-Mar-02 AT 01:15 PM (EST)]No it was never fuel injected here in the states I don't know if that is true for our Aussie friends though. There is a company the name escapes me at the moment but i will look for it that will make a multi-port FI system for your 400 which is about a highly efficient as you can get. But your ignition system will still be older style which is much better by my experience and has more possiblility for customizing. The only tough part is that it cost $3000 for the complete system. Although I do have to ask you what did you not like about the Holley system?

Thanks for the reply. As to not liking Holley's, it's not that I don't specifically like/dislike them, it's carbs in general. I used to be a mechanic and now that I'm an electronics tech in the aerospace industry, FI is definitely the way to go. No worries with altitude, attitude, or engine temp. With fuel injection, the system can be tuned continusly while driving, and it doesn't matter what the atmospheric pressure is, the engine will run the same.

Once the fuel maps have been ironed out, it's as close to a "perfect system" there can be.

Plus, I really dislike carbs, just incase you didn't get that from my previous ramblings.

The EEC IV was one of Fords 1st attempts at a computer controled system.And to say it was not one of Fords better ideas is a understatment.This was not a good system. The only good thing about it
was that you could remove the variable venturi carb and locked down distributor and replace it with a motorcraft two bbl carb and duraspark ignition.Some of the later 460S are F.I.Ask around about the EEC IV before you go yhis route.Good luck

I'm currently in the most fledgling stages of fuel injecting the 351M in my '77 F-100. If money were no object there'd be a million ways to do it (starting with Holley Projection and increasing in price from there), but since for me money very definitely is an object my options were limited. I personally don't have anything against carburetors other than the fact that they are by definition less efficient than a well executed EFI system, but I wanted to do something "different" on my truck and hopefully get better power/economy at the same time

I got involved in a group buy on a DIY programmable fuel injection computer designed by two gentleman named Bruce Bowling and Al Grippo respectively. The unit is called a "Megasquirt" and and while the buy included all the parts, you must assemble it and adapt it to your vehicle yourself. There is a very active list of VERY bright people who also were involved in this purchase - check it out here:

The MS will support Multi-Port or Throttle-Body injection, but for simplicity's sake (and budgetary constraints)I'm currently focusing on using a TBI set-up on my 351M. The most likely scenario is that I will scavenge the throttle body and sensors off a late 80's GM truck - may the Ford Gods forgive me... I will of course have to make an intake adapter and figure out a means of hooking up my C6 kickdown, but those are obstacles it shouldn't be too hard to overcome.

I haven't started on this project yet and I'm sure there will be unforseen snags along the way, but when all is said and done it should be something of which I'm quite proud. At least that's the plan anyway...

K. I don't want to start any pissing matches, but I've only heard about bad things about carbs. I currently have many friends running 4 bbl holley and 4 bbl carbs. Ihaven't heard ANYTHING bad about them. I hate these new cars coming out with sequentil port fuel injection , Multi Port Fuel Injection. I really disagree with the EPA, and "Air Care" up here in Canada. I mean honestly, kids these days are learning more about their vehicles and learning how to get more horsepower out of them.....whether it be headers...exhaust, high compression piston...etc....and still manage to pass their locoal vehicle specs............My Great Aunt was hit by one of these "RICERS".......Honestly it pisses me off....It's hitting me too close to home and I hope he dies




Sorry this is really off topic, i 'm a lil' drunk

 

I myself was considering multi-port efi for a 351C/351M/400. Here is what I was thinking:
i) take standard edelbrock 4 barrel intake and have injector bosses welded to the intake runners (as close to the ends as possible).
ii) have a machine shop drill/bore through the injector bosses/runners for the injectors (19lbs/hr).
iii) use the air intake from a 460 (throttlebodies included) custom mounting of air intake to manifold if req'd.
iv) computer and harness from a vehicle of comparable weight and would have to have an engine of the same firing order (for the injection sequence).

My downside is that I am not adept at wiring such an animal but I sure would try.

There's a web site, I think it's http://force-efi.com/ that I'm currently working with. I'm building a 400 for my '79 F-350 supercab 4x4. It's going to be setup with a Holley Commander 950 system, it can run either a throttle body type of fuel injection or a multi-port fuel injection. I choosed the multi-port route and what they had me do was send to them my manifold (Eldebrock Performer)and they setup the intake manifold with the injectors and fuel rail installed and send it back to you with the complete (we'll see)system with a base program installed in the computer. It's a bit pricey at around $3000.00, but I've had this truck since it was new and plan to keep it instead of buying a new one. Call me crazy, your not the first.

 

Make an adaptor or go to holley and ...Pro-jection-4 which ix totally like the TBI on GMv8's, but Holley base style. I look also to the MAF systems on 89-up 5.0 cars with a bigger maf-tube and corresponding injectors(i.e.24's or 30's and proportionally correct maf) This overcomes the non-maf regulated part of the written program (idle etc.). Sizing goes proportional to the 302 to 400 inch size difference, or 33% bigger for a start. Hacking up any manifold of your choice is now possible and 302 fuel rails will do, due to the 4.38" bore centers. Truck efi's twin hole throttlebodies are good for like 750cfm too with all the hardware in place and must match the computer brand you use. Been there, done that, four conversion jobs behind me, some yet to be de-bugged. Bruce T---81 bronco,351efi, 84van460efi intercooled too(you guess the rest),86 mini Slowpar van was carb'd. and 383 done with a buddy.

 

wont a 460 intake fit a 400? i know the heads will. if so you might be able to use the 460s FI on the 400.

 

I'm sorry but the heads from a 460 Will not fit on a 400, bore spacing is all wrong ...

 

A word to the wise. Ignition interference is a big concern for a fuel injection computer. I tried to use the Barry Grant VFI system. It acted crazy and eventually drowned my engine with fuel one to many times. I had to build a new one. The tech people were no help at all. I was able to send it back for a refund. Of course that didn't cover the engine damage.
A few months later a trouble shooter called me about it. Said it was fine on the bench. Asked if I had a hot coil (Accel "E" type). Said that was the problem. Interference. It would have been nice if the tech had not told be my ignition was not a problem.

The EEC-IV has nothing to do with the Variable Venturi Carb.
It is the SD and MAf system,s used from 87 to at least 94.

I was looking for fuel injection information on my 400 ford in my 79 f-250 4x4 when i came across this topic. It was listed on a search engine response. After reading the posts i decided to see if you were able to find a suitable system. I know that it has been a while since this topic was discussed. If you haven't found a suitable system, i suggest looking at the gm t.b.i. System offered by turbocity. You can reach them at turbocity.com via the internet. They offer a complete t.b.i. System that is customized to fit your specific application. They custom make each wiring harness and customize the electronics to fit your needs. These systems are advertised for around $1,200 to $1,400. You may need to create your own linkages and use an aftermarket distributor w/ magnetic pick-up to complete the installation. An aftermarket intake will most likely have to be used also. There was one testimonial on there from a man who installed the system on a ford van with a 460 engine. He praised the technical support team for giving him unlimited help with completing his installation. They also offer a variety of performance inhancing parts for this system. The good thing about this system (other than the relatively low cost) is that they advertise that all parts are delco supplied and replacement parts can be purchased from any parts store. As soon as i am able to scratch together enough money to complete my restoration job on my truck, i am going to purchase one. If you or anyone else has any further information on this system, i would appreciate your feed-back.

THANKS, b.h.
