first, dont let the low post count catch you, I've been on the boards for a good while and first cut my teeth on 71-73 mustangs back in the early 90's (I just wasnt on this site for about 3 years and literally forgot my password on my older user name haha).
actually, here's an older pic of both my brother and I's cars:
![Image]()
the yellow one was mine and we built the black coupe for him from the ground up. mine is gone now (had to sell back in the college days during a tuition crunch) but he's still got his.
been trying to talk him into switching over to efi on it for a while since I honestly dont think it will be that hard to convert a cleveland over.
There was a webpage I had saved a while back about a pantera over in sweden with a fuel injected cleveland running off of a hacked up 351w fuel injected intake and an EEC-IV. Anyone know the link to this site as I lost it when my computer crashed last year?
Also, I know all about the efi spyder intakes...
Here's where I come into the questions, I've started sketching out what to do as far as getting it up and running under fuel injected status since it's getting time for the 2nd restoration of the car anyway. I figure this will be a nice christmas present for him.
Intake
modify a normal lowrise cleveland intake manifold with injector bungs and do an upper like off of the spyder intake. I've got a metal supplier I use where I can get a 90 degree aluminum elbow and cut to fit. Probably end up mating it to a 1" holley carb spacer or something along those lines. Basically, just keep the intake as simple as possible to start with to get it running efi wise.
Wiring
EEC-IV ecu/harness/fuel rail/injectors from a 5.0 thunderbird (easier to find than a mustang). Rewire the injector harness to match the firing order of the cleveland and remove all the misc. wiring that isnt needed. weld some supports for the fuel rails to the intake and mount the injection and be done.
ignition
Probably just use a factory efi distributor from a fuel injected 460, again so we could get it up and running. Then he can do whatever he wants with it.
Engine
fabbing a blockoff for the fuel pump and possibly having to add some various sensor bungs in places is about all I can really think of.
Fuel system
here's where I havent done much exploring as of yet. Pretty much do you think the factory hardlines can support the pressure of a fuel injected system? We would be retaining the factory hardlines and this is what has the question in my head. Also, which way would you go? intake fuel pump(s) or inline fuel pump(s). I dont see where it would be very hard to modify a stock intake fuel pump pickup and a stock 71-73 fuel tank so that the two fit, just time consuming is about all I can really think of. Plus, getting a walbro off ebay for an intake setup upgrade is definitely cheaper than getting a high $$ inline pump.
Am I missing anything?? I've got a few more questions in my head right now such as if a 5.0 ecu can read the tfi signal from a 460 distributor? Pretty sure it can but you never know what those crazy ford electronics guys did, I've seen stranger things.
Anyway, I'm just writing this to get the feelers out there since I'm in the drawing board stage on this project (which I've been trying to convince him to do for the past 5 years hah). Though, it would be extremely easy to kick it over into fab mode since we've got all the parts needed laying around and then some.
let me know what you think/suggestions/hate about this approach.
