Fuel Injection for a 75' Lincoln

I have a project car, 75' Lincoln Cont. I want to swap over to fuel injection from the carb. Is this doable? I was thinking about finding a late model motor and just swap it for what's in the car now. Comments? Thanks Todd

Sure.

The easiest way that comes to mind would be to pull a processor and harness out of a 1988-1993 Mustang 5.0. You'd need to add injectors and rails to your carb intake and add an EFI elbow, idle-air valve, and throttle body. You'd pick injectors and the mass air meter to meet your fueling requirements, and put together a fuel system. Then, you'd buy a Tweecer or a chip to tune it.

You could convert the whole thing for probably $1500 if you do the work yourself and source the parts from boneyards and it'd run like factory.

If you want to use aftermarket EFI, look into megasquirt, bigstuff, and FAST. Look at Mass-Flow too; but that's basically OEM Ford as suggested above...you can do it far cheaper on your own.

EFI

That boat has a 460 in it. Use the hardware from a 87 or newer F-250, E-250...wiring, processor, aftermarket fuel pump, weld a couple of bungs in the exhaust for O2 sensors. You should be able to swap out the motor...just not sure about the balance...internal vs. external. Try to find a wrecked or salvagable donor....

ZX3 is trying to help and that's appreciated... but, the stock efi 460 setup won't allow you to run a cam of any size as it's speed density unlike the mass air setup of the mustang efi. Also, the factory efi 460 intake, with upper plenum, is very tall and wouldn't come close to fitting under the hood of a continental (it's ports are configured for EFI heads too, which are different). I'm with Byron on this one, use the mustang EFI and adapt it over or go with Megasquirt. I don't know 1/20th as much as Byron when it comes to EFI, so listen to him and he'll point you in the best direction.

Ok, I'm a little confused, So what machine work would be needed to adapt the later Mustang FI system to my intake? I'm a machinst by trade so that part doesn't scare me. Is the Mustang system a true bolt on or not? Thanks for the advice. TH

Bolt-on.

The 1988 460 truck EFI distributor is a bolt-on.

The 1988-1993 Mustang 5.0L harness (or the aftermarket harnesses) is a bolt-on, with deletions because it contains a lot of stuff you won't need/use. The computer (PCM) is also a bolt-on.

The intake manifold will be a carb manifold with injector bung modifications and an aftermarket intake elbow/throttle body bolted up top where the carburetor used to sit.

Look at my stuff. http://www.racesystems.com/cobra

Fuel rails can come from Probe Industries or anyone else that makes retrofit rails for 460 Carbureted manifolds, or you can buy fuel rail stock and machine it yourself.

Air meter (tells the computer how much air mass is entering the engine) comes from a variety of places depending on the power you're going to make.

Fuel injectors come from a variety of sources again depending on the build and power level.

Sensors come from Ford.

Fuel pump comes from a variety of places, like Weldon Racing, etc...depending on your goal/needs.

Lastly, you buy a tweecer. www.tweecer.com to reprogram the computer for your engine displacement, injector size, injector firing sequence, and whatever else you need.

Basically, just pretend it's a big 5.0L Ford, plug it all together, and tune it with the Tweecer. And if you need a part, the Ford dealer has them.

Take a look at this for rails and bungs...and the required manifold mods.

The intake elbow you choose must clear the hood, flow enough, and have provision for a Ford IAC valve. I made my own. Are you a CNC machinist? I designed mine in Solidworks.
