I'm trying to put a 96 EFI 460 into a 78. I've heard Helm's manuals are really good wireing diagrams. Does anybody have one. How good is it? Could you scan a page and email it to me. I got Mitchells and Haynes. But i want one that follows the pluts instead of where the wires go.

I am assuming you meant plugs

do you have all the wiring out of that 96 including the computer
that should have OBD II system I am doing a 78 using the 95 stuff
I just got the whole harness including the engine compartment and omitted the unneeded stuff like the lights and other stuff
just keeped the stuff that came off the computer plug
if you are using a manual or C6 tranny you only should have about 8 wires to hook up if you are using the E4OD like I am then you have about 17 wires to hook up to the truck
I am not sure on what you are trying to do with the plugs though

The 460 didn't go OBD-II, unless maybe in cali...
Anyhow, it's a very simple hookup, once you remove all of the non engine related components of the harness.
FWIW, Helm manuals are the Ford factory service manuals, and the electrical sections just plain kick ass...
I'd suggest maybe picking up one of the service manual CD's off of e-bay.

I'm with 82F100SWB. I have a service CD and it has it all. Why would you want EFI for a 460 though? The EFI is VERY limited for that motor, you would get much more out of that BB with a good intake, cam and carb combo.

Actually its out of a 97 and the 460's NEVER went OBD II because they were over GVW ratings. I was baffled myself. Most everything on the motor is dated 96 but i thought i found one or two things that said 97. The computer is a F6TE. See my problem is I didn't pull the harnes and I don't have a buddy with a 460 for me to compare too. I put a EEC IV computered 5.0 in my Ranger. I'm sure it's very similar. I just want to make sure I get it all right. I'll have to get me a helm's then....

my engine compartment harness came out of a 92 with a 302
and it matched up to the engine harness just fine it had a couple of extra wires that the 460 doesn't use but the pinout to the computer matches between a map 302 and a map 460
so if you did a conversion already you are set just find a 92-95 truck in the wrecking yard and grab its harness

That is very good to know. Good stuff info.

BTW, the stock 460 injection is only limited by your imagination. With mass air or speed density, you can do just about anything with the right EEC mods.

Actully the above statement not true 460s went OBD2 in calif in late 96-97. They were SFI and MAF with an 80mm mass air meter. They used 24lb high flow injectors. They are the best running and and get the best fuel milage of any of the EFI 460s. I have a 97 that Im in the process of puting in a 73 F250 crewcab SB.

you got me there.... i forget about yall out yonder..... see i'm in Alabama........ just a short drive from california emissions. Well i thought i had the best but i guess i'm wrong..

I have been inclined to belive this already in my looking around junk yards. But I hadn't heard anyone conferm this before. I got the harness just need to figure out where the crap goes...

While this is true, a mass air conversion is $$$. So are any EEC mods. The only good thing about it is the ease of the bolt on supercharger by Vortech. If you wanna build a torque monster going with a good carb with good heads and the right cam is infinitely cheaper then trying to get something that works with the EEC and doesn't throw codes all day long. But... to each thier own... :)

carbs are old outdated stuff for people that cannot accept change

how many carbs you know that can run in any angle thrown at it
or not have to be pumped to death in the cold to start the rig
and can constantly adjust itself for the best fuel ratio for the given circumstance it is in less the a seconds time :)

the only carb that I know that can even come close was ford varaible venturei carb in the mid 80s and it was a piece of crap ;)

Yes carbs suck..
But, factory 460 EFI sucks... the heads suck compare to carb heads, the computer has to be replaced, and so on...

As for cold weather starting, my 460 goes on the second revolution EVERY time, no matter if it's 70 or -40, one pump to set the choke and it fires up...

As for EFI being able to adjust to the "best" mixture, it can do stoich, but, due to the narrow band 02 sensors OEM's currently use, they can't go lean at idle, or at part throttle criuse like a carb can. I notice the idling issue alot during the winter due to the extended warm up times necessary due to the extreme cold we get here. My car(Chebby Cavalier with a 3.1, MPFI) consumes more fuel during extended periods of idling than my 460 does.

A classic example is a carbed and EFI 300 I-6, the EFI engine has a better head design, better manifolds, and higher compression, so, it should be the more efficent of the two, but, compared to a carbed 300, they are a gas hog....

I dont agree in 93 Ford went to larger valves in the EFI 460 heads not as big as DOVE or CJS but big enough. The port config. is better in the newer EFI heads they have great volicty which = great throttle response. I gess it depends what your going to do with it. I need a 460 for torque lots of it and I really dont need it to turn over 6000 RPMS if even that.
MY two cents Leadmic

What about putting the EFI stuff on lets say a 70 model 460? I say a 70 model since that particular one is 500 foot pounds right out of Dearborn.

I remember reading something like that recently. I just don't remember where I read it. Supposedly, the later EFI heads are supposed to be the new rage since all the DOVE and CJ heads are drying up. That's what I read anyways......
