5.0 swap

Probably asked before but how difficult is it to do a swap to a 5.0 from a dual plugged 2.3. And would it be better for me to do a carbed or fuel injected swap?

Thanks for any input

I don't usually read post about engines because I'm not that skilled with them but I do know now that I need a donor car with the engine, computer, wiring harness, and the transmission if I want it to be an easy swap....

Thanks

Re: 5.0 swap

Having an entire car is the easiest way to go. Find a 5.0 some kid put into a ditch and start from there. You'll also need suspension components, brakes, rear end... There's a lot you'll need to do it right and a complete donor is probably the cheapest way to do it.

not tryn to sound negative, but if you arent skilled with "engines", a swap is probably not a good place start. like first year med student doin major surgery. dont get me wrong, everyone has to start somewhere. i hope you got a knowledgable person to help u wit da swap. good luck

My dad is going to be doing a bunch of work with me helping some and he grew up working on motors and is very knowledgeable with them... So I figure we'll be fine

Re: 5.0 swap

Alright, I've been doing some research on the conversion and what I know so far and correct me if I'm wrong on any of this. I will need to get new fuel rails to run to the engine, and an 8.8 rear end. And lots of people say that I can just get an sn95 rear end and drop that in there and then I'll have disc all around.

Re: 5.0 swap

I think the SN95 rear is a little wider than the ones in the fox. Someone correct me if I'm wrong, but thats what I have been told. You can get an 8.8 out of an SVO and you will then have rear discs, and I know those will fit perfectly.

Re: 5.0 swap

I'm in the process of research and parts list creation. Been reading through some post on other forum's and they said the sn95 bolts right onto a fox. Not sure but if I can get one cheap enough I'll give it a shot and if that doesn't work I can always re-sell it

Re: 5.0 swap

It will bolt up no problem, but I think the rear is wider is all. If you did put one in you might have to get some different offset wheels to make it look right.

Re: 5.0 swap

Hopefully I won't have to but if that ends up being the case I'll sell that rear and just get an 8.8

Re: 5.0 swap

Ok, my mistake on the '94 to '98 rear being wider, it's actually the '99 to '04 that is. It is close to an inch wider, so your plan will work!
Sorry for the misinformation bro!

A complete 94-98 8.8 disc brake rear end is wider than the 93 and under drum brake rear ends. The housings are the same but the 94-98 Axel's are like 3/4" longer than the 93 and under ones. I have a complete 94 disc brake rear end in my 86 and I had to do the following for it to be right:

1) Different offset wheels so they wouldn't stick out past the fenders

2) a special plug is needed for the proportioning valve to force more fluid to the rear since disc brakes need more fluid to operate than a drum setup.

3) an adjustable proportioner needs to be added in the brake line where that coupler fitting is located against the fire wall on the passenger side to balance the front to back.

4) the stock e brake needs to be modified to eliminate the automatic tensioner and made manual or it can cause the back brakes to drag.

5) the fixed cable on the e brake needs to be replaced with an adjustable one

6) depending on the year of the car sometimes the master cylinder needs to be replaced with one that has a larger piston in it.

I may have left out a couple things but I'll look for this link I found a long time ago that has written instructions for just about every configuration you can think of.

Or you can get a 94-98 8.8 rear end and put your Axel's and drum brakes on it and be done. Ive done that a few times too. If you go that way you need to be careful since the flexible brake line on a 4cyl car that runs to the rear end is not in the center like on a v8 car. If you run duel exhaust with out addressing that issue that flex line is real close to one of the tailpipes where it humps over the rear end.

Re: 5.0 swap

Thanks man, might just use a fox's rear end. Do you know if any of fox's had an 8.8 in them?

Re: 5.0 swap

That's what I thought, see I knew it was wider dammit!

Any fox GT or LX 5.0, 85+ will have the 8.8 you need!

Paste this link in your browser. Page 8 talks about the sn95 rear. This is an awesome guide for brake / rearend swaps and has saved me tons of time and money.

Go with a fox 8.8. Now a days you can find some pretty cool wheels that are 4 lugs, unlike back in the day when your choices were either 16 in. Chrome pony wheels or 17in. Cobra Rs. Now for the engine swap....plan on spending upwards of 2,000 bucks just for engine swap parts. This doesn't include the engine or trans. Who ever mentioned a donor car is exactly right. I once helped build a buddy's 4 cyl to 5.0 project car and it was a beast.. You'd probably come out a lot cheaper bolting on a turbo kit and calling it a day!! You'd have a pretty cool sleeper that gets great gas mileage!! My .02

Well we've got a donor car lined up. I just have to come up with $300. It's a 1980 carbed 302 running but a really rough body so I'll be getting that and taking the motor, trans, computer, and any thing else I'd need for the swap so hopefully we won't have to spend much more than that

The 80 had the very fragile 7.5 in. Rear end! It sucked. Nowhere near as strong as the 8.8. Want a really good running street engine combo? Go GT40 iron heads, edelbrock street performer intake and a 600 cfm edelbrock carb. Comp cams makes some pretty good magnum series cams for carbonated mustangs. It's cheaper to stick with carbs vs EFI. Obtw... The 80 302 engine uses a flat tappet cam vs 85-95 EFI 5.0s which have roller cams. The rollers are smoother, and more are more aggressive with better drivability. FYI!!

Yeah, thanks for the tips. I'll see if the budget will allow for some upgrades before we drop the motor in

Re: 5.0 swap

Wish I was closer to you, would probably buy the body from you when you were done with it. I need a good drag car project! Might be doing something with a 460 in a fox soon. Just have to see where I'm at with the money situation!

Re: 5.0 swap

Lol, that's what I was thinking too. I just hate the dash's in pre 1987 mustangs so I'll have to take that out and make my own . Won't realistically get it done till after college because I won't have the funds...

Re: 5.0 swap

When you do a swap you need the wiring, the computer, driveline, and the rear end. I think efi is better, i have carbourated, i might end up switching it. But then i have to put everything back on for efi. And efi is better on gas. But then youll; probably run into more problems, and codes and stuff.

Re: 5.0 swap

Well the only option I have right now is this carbed one because I haven't been able to find a efi one. Plus the body on this car is in pretty good shape so I'll probably build a drag car out of it:

Re: 5.0 swap

That looks like an 85-86 front end. Is that the 80? If so they must have swapped the front. Looks pretty solid though.
