I've read the tech article on this site and at Windsor-Fox, but would like some clarifications...

My motor has a '85 non-roller block and '77 heads.

Please explain the firing order issue. From what I gather some type of modification would need to be done to the harness to allow the early firing order?

The donor car might possibly be an '88 Lincoln.

I will install an inline electric fuel pump and can fabricate a return line.

I do have trouble locating a source of hard plastic, or other material, for new fuel lines. Any sources you are aware of? I'm not sure the standard steel brake/fuel line I can get at my local auto parts store is EFI approved. Rubber is no prob.

Any suggestion or comments are welcome.

 

Have you tried your local Ford Dealer? One of our local dealers has the tubing, the push-in fittings and the tool to make up the fuel lines. He made up the fuel lines for me a couple of years ago when I installed a F.I. 5.0 in my '57 F100

 

Good suggestion! I usually stay away from the dealer.

I've found aluminum lines and adapters on the Summit site. Looks like Earls is the ticket for the lines.

I 'won' a EFI system on Ebay for $210 shipped from an '88 Lincoln.

Now I;m looking at another auction for the computer from a '89 Mustang, wiring, distributor, Maf and O2 sensor et al.

Guess I'll need to sell the Holley 2D system I bought....

The Ford EFI system might be more of a hassle, but from my research it is far superior.

 

I agree that you will be better off with the Ford system.
I didn't take the truck to the dealer to hve them install the lines, but rather took the measurements of the fuel lines I needed and they made them up. Was actully quite reasonable when all done.
I've done two 5.0 HO conversions and love them both. One in a '49 Merc and the other in the '57 F100. You might want to look into an aftermarket wiring harness to simplifly the installation, though. I have used a Ford Motorsports harness and a Ron Francis Harness. The Ron Francis harness is a little more pricey, but makes a really neat installation if you take your time.

 

hey i have a question. i was going to change to a 4 bbl carb set up on my 302 with 84 block and 77 heads. i have thought about efi and have read the article also, is this very hard to do or can a novice take a lot of time and do it. just wondering!!!! i would love to have efi in my truck if i could do it.

 

Depending on your skill level, of course, but I didn't find it all that difficult. I am not a mechanic by trade, but rather just a hobbyist.
I certainly would recommend a donor car if you can find one. I like the Mark VII's from about '87 up since they use the 5.0 HO setup. The only downside is that they are speed density rather than Mass Air systems. And, as long as you are going to keep the engine stock, speed density is fine. It is nice to have all the pertinent fittings, etc. I would also recommend an aftermarket harness of some type to simplfy the wiring.

Good luck

Thanks i do plan on leaving it stock if i go with the efi, which i want to do. i only plan on adding mustang shorty headers and an X pipe. i'm also a hobbist i have done a lot more to this truck than i thought i could by just taking my time and studying the instructions, and looking at what i'm going to be working on at the time quite a while before i get started on it! Thanks again!!
