the 5.0 EFI in the late 80's Lincolns and any other 5.0 EFI in a Mustang. I know the crank has more support on the H.O. and Boss blocks, and the firing order is different, thats about all I've been able to find out. I'm wanting to build up the internals of my Lincoln, its a 1987 Continental Sedan,(just wanting the thing to live for the next couple decades by my side, running strong ) things like Camshaft, Pushrods, Lifters, Valves, Valvesprings, Rocker Arms, etc. Am I able to go about buying performance parts of a Mustang to put in my engine? Or are there other things I should know? No one really has any info about it, and yeah, I know the Lincoln weighs 4500+ pounds, but I'm not racing or anything, just want me an old luxury car with a strong powerplant.

As far as I know the internals are the same between the base model 5.0. I know you can swap engines between the mustang and lincolns and all you have to change is the bolt on parts.

 

[89BlkNotch]

everything should be the same except the camshaft since the firing order is different

 

[DEMoNik623]

ECU is what I'm wondering about...

I know with the firing order being different, cam, distributor, etc. needs to be changed, but what about as far as ECU goes? Would I be looking at having that changed, or retuned or something? Being that there is a different output engine in it?

 

[cenok is family]

only things different are the cam and intake manifold. everything aside from accessories are the same. any "mustang specific" parts will work on your car, even camshafts. just have to rearrange the the plug wires on the distributor. ecu is going to be different though. just keep yours, it should work just fine.

 

[need4spd90]

99% sure you'd need a different computer..im fairly certain most of those lincolns were not mass air cars

you'd need an A9L or A3M for a mass air HO mustang 5spd
or an A9P or A9M for a mass air mustang automatic

thats assuming you want your mustang to be mass air,not speed density,otherwise you'd need a speed density mustang computer

im sure you could use the ones from the lincoln if you were running speed density in the mustang,but lord only knows how weak the factory "tune" is on those

Performance is what I want

Nothing ridiculous or anything, but more than what the lincoln setup puts out. Is anything else besides the ECU needed? I'd be able to just buy one and plug it in and it should know whats going on with my engine? I'd most likely be needing a Mass Air Flow Sensor as well correct? Now what are the pros and cons of MAF vs. MAP?

Well your intake manifold is backwards :rollgrin:. I did this a long time ago on an old 2 Door Crown Vic I had. Just did an HO swap and took a cam, intake, heads, computer and thats about all you need. It will wake up that old box though! The DOA will have problems shortly after, the increased power coupled with 5k lb weight will kill it. To get more info on the swap(it is VERY common in the Panther platform cars) visit CrownVic.net and they will show you, step by step, with pictures, on how to do it.

 

[DEMoNik623]

Lol. I was sitting here for a little while trying to figure out what the DOA was. Lol. From what I've heard brand new, the AOD's are good for 500 HP. But I always hear of people putting the Tremec trannys with their 5.0s. As for that Crownvic.com, could you be a little more specific as to where I'd be able to find that procedure full w/ pics on the site? I did a little browsing, and wasn't able to find much that helped. IDK anything about the Crown Vics of that time, I'll guess Ford put the 5.0's in them at the time, and the 5.9's in the Police Interceptors, being that those were their engines at the time. As far as the layout of the engines of each Model, I don't know much.

Thanks, but apparently My E-mail address is banned there for some reason, even though I only visited it the one time the other night. Wierd. But, I wanted to post a q on that forum, Poster of that thread says that the ECM out of a Mustang will work, without changing anything. How would that be since the Mustang has a different firing order than the base 5.0's? Does the ECM only control the fuel flow? And if so, from there, wouldn't I be looking at changing my distributor wires around to follow the H.O. Firing Order? He also states a good starting point is ECM from a 86-88 Stang (I have an '87 Continental Sedan), E7 heads (Not sure what heads I have, anyone have an idea if it's stock?), 19lb injectors, Upper intake, throttle body, and an H.O. Cam.

 

[Tempted]

The reason you use the Mustang ECM is because of the firing order. The ECU, cam and MAF should be used together from a Mustang.

 

[DEMoNik623]

That makes more sense to me. I couldn't figure out why he was saying that a Cam isn't needed with just a Mustang ECM. In my mind, ECM is controlling fuel flow I.E. EFI, with that being the case, my cam is still telling my valves to open to the timing of a Base 5.0, not an H.O. 5.0. So my valves would be opening with the firing order of 1-5-4-2-6-3-7-8, and the H.O. ECM would be injecting fuel into the engine in the 1-3-7-2-6-5-4-8 firing order. Without a cam, it would probably get an initial crank over, but after 1 fires, 3 would be getting fuel, but the valves for it would be closed, along with spark not igniting in the same order. So ECM, and Camshaft are my starting point then, along with rewiring my distributor, or get a new one (Most likely case, MSD :bigthumbsup)? Also, wouldn't I need to modify my valvetrain to match the lift of the new camshaft?

Not with an HO cam. You can use your stock springs but if you go with something bigger than stock you will need to start upgrading. Now the question is can you buy the HO parts and install them cheaper than you can buy an HO or Explo complete motor. I can pick up an Explo 5.0 for about 500 bucks around here.
