If so, which factory or aftermarket system did you use?
Did things go smoothly and are you satisfied with the results?

 

Most guys on here have done the mid 80's conversion before EAOD transmissions.

The computer chip calibration I understand can be set up to the specs of the 70's truck.

 

I put a 302 EFI in my 79 2wd. It came out of an 88 E-150 van I got real cheap. The pickup isn't much either; the whole project was kind of an experiment for a hopefully a nicer rig in the future. I wouldn't do it without a complete donor vehicle. It didn't go too bad for having a tight budget and short increments of time to work on it. Here's a couple that came to mind about mine:

-Wiring probably took the longest time. I spent hours studying the van's wiring diagrams and modifing its engine harness to work on the truck.
-I used the fuel system including the rear tank from the van but plan to go with a single high pressure in tank pump and neater fuel lines sometime.
-I also kept the serpentine belt, so had to wire the charging system for the newer alternator; and custom made a power steering pressure hose.
-I had to use a front sump oil pan for my 2wd application, and I still need to find a timing cover that will allow a reverse rotation water pump and a front dipstick.
-The air filter box and hoses won't fit in these trucks (V8 anyway) so you'll have to figure out something there. I used a cone shaped open air cleaner and the factory tubing from a 96 that had mass air.
-The smog tubes going to the back of the heads won't clear the firewall. I took the entire AIR system off except the TAB and TAD solenoids and plugged the holes with short bolts.

The truck had a 302 before so that made it somewhat easier. I kept the C4 trans for now but have an AOD to put in there someday. Let me know if you have any specific questions on the swap.

 

brown 4x4,
I was originally thinking of doing a factory efi swap and still may do so since I already have most of the parts. I'm just looking at some of the aftermarket systems which seem to be much simpler but there are so many choices, it's difficult to decide which one would be better.
It did'nt even occur to me there would be an interference issue with the air tubes and firewall, I was intending on using them if I went that route. Thanks for that tip.
Try Ford Racing for a timing cover that uses a reverse rotation w/p and front dipstick tube. I got a timing cover and water pump off Ebay from someone who got them on a Ford Racing crate engine and decided not to use them.
As far as the air filter box, I was thinking about using a mustang intake and rotating it 180* and put the air filter box on the drivers side like the Lightning.
Thanks.

 

Thanks, I'll have to check Ford Racing for that timing cover. That's probably the main thing keeping me from driving it (no dipstick). I'll have to look at how Mustangs run their air intake and maybe give that a try. I don't like the way my current air intake looks at all. There's a few pics in my "other trucks" gallery.

Aftermarket systems are indeed simpler. What I don't like about them is the fact parts are going to be harder or take longer to get. Also diagnosing a problem seems so much easier with a factory system.

 

I did a MassFlo EFI on my 400 and am very pleased with the performance and milage. I'm still not sure about the Mallory frame mounted fuel pump though.

 

I'm just starting an EFI 460 swap in my '78, the motor will be out tomorrow. I will also be converting it to mass air. I will be making another section in my gallery with progress pics, and will be posting as I go along.

 

Sounds like a nice swap. I would start on my 78 Supercab tomorrow if I had a donor 460 EFI truck and the funds. I'll be interested in your progress. How are you converting to mass air?

 

Has anybody done,or heard about doing a gm tbi injection swap off a late 80s gm truck?I read about it somewere on the web and it seemed pretty easy.If I find the site Ill post it.

I found it check it out http://groups.google.com/group/rec.a...b92371f78050e6

Anyone done this?

 

I saw a few articles on the GM TBI swap. Here's a company that sells complete kits; www.howellefi.com I've never spoken to anyone that's done that swap, so I can't make any reccomendations on it.
I've finally decided to go with the Mass-flo EFI system for my truck, I just ordered a kit the other day. Everyone that has one seems to be pretty happy with it. It's a mass air, port injection system that uses a 85mm LS1 Corvette maf, and the rest of the electronics are 89-93 mustang 5.0. So, if you need any parts, they're at your local auto parts store, and you can even check for trouble codes. It also uses a Victor jr. style intake with a progressive 4bbl throttlebody.

 

I installed an EFI 300-6 out of a 92 F150 in my 78 F150 that had a 300-6 1bb originally about 12 years ago. I couldn't be happier with it. I haven't had one problem with it (now it will throw a rod.) It took some time to rewire, but the 92 tank and in-tank pump fit right in the frame, but the gas guage does not have the same characteristics as the 92 pump (reversed and different ohms at full and empty.) Mechanically it was a 1 for 1 swap - used 78 oil pan, flywheel, etc. It always starts right up, gets good mileage. Good luck with your swap.

 

I have already installed a 93 4.6 liter 32valve engine and tranny in my 79 F100
still have lots to do with cab mods and rear end, but I am reusing the entire harness and computer from the 93 Lincoln Mark 8 doner.

 

Have not done it yet but I have the pieces from 2 crown victorias. Read somewhere the 86 to 90 harnesses were the easiest to use. The battery is on the same side as the trucks and the throttle body is on the drivers side. Computer is on drivers side also, need to see if it can be flipped and put on passenger side. It is the SD system. I put a mustang engine in my 87 Grand Marquis, flipped the intake, had to do some work on the throttle body and egr assy to make it fit the merc, plugged in a computer from a 87 mustang and it ran fantastic.
