Anyone here running one now? What are the main drawbacks over a GT or stock 5.0 lx? Frame reinforcement? Lastly, Will a stock 5.0 HO motor hurt my lx frame?

I guess i don't get what your getting at....? Main drawbacks over a GT or stock 5.0 lx? Um... nothing? Unless i'm mistaken, the body is the same regardless of the engine. A 4 cyl is actually better if you plan on putting a new engine in it anyways. First its cheaper and 2nd the frame should be straight because the 4 banger doens't have enough tq to hurt anything.

Are you actually being serious? Or are you just being retarded? Pretty sure you'd put ATLEAST the stock 5.0 brakes on it if not sn-95 brakes when you put an 8.8 underneath it....

Well I don't have a 5.0 mustang as a donor car. This engine is coming out of a 91 T-bird.
I wasn't trying to be retarded, I just wasn't sure how large a problem it would be. I didn't know if it would be like "Damn this thing is heavy" or " OH S**T JUMP OUT!!!"

5.0 motor

first off what are you building the car for is it you just want a v -8 to have more power or just a full out car car that you my drive on the road. the 5.0 out of a thunderbird is not the same as the 5.0 out of a mustang. it will just bolt in but the tranny cross member needs o be a v8 for the double exhaust. the fuel lines have to be changed. the brakes off the 4 banger will work if you just street drive it and a little racing good luck

For right now, the plan is just to get it street-able. I know the T-bird 5.0 is different, I'm hoping that for right now it will help a little with gas. The plan is to drive this while I work on my 300zx then when that is finished switch up and upgrade the crap out of this one.

First of all....I agree with 1990Coupe. Why would you answer someones question like that??? You should be :ban:

Now, to answer the thread starters question nicely....

All the Mustang bodies are the same no matter what the motor size.

The front suspension is "different" because of supposed better ball joints/bushings in the LCA's. Thicker sway bar, struts and spindles have different thickness where the strut bolts up, and all 5.0L cars of course have bigger brakes.

The rear end in 4cyl is 7.5 drum vs. 5.0L 8.8 drum.

Now if you do this swap. You can use all the front suspension from the 4cyl. However, I would recommend swapping to the V-8 spindles, struts and brakes. You can keep the 4cyl control arms and K-member, even the springs. My notch is a 4cyl conversion. I have the 4cly front and rear springs. It sits very nice.

I drove my car around for 1 month with the 7.5 rear end, until my 8.8 was built. I then swapped it in with all new control arms and brake hardware.

Here are some pics for your enjoyment.

Wow man your car looks great! I will be running this thing sans-interior. It will be a driving machine. Everything it needs to go down the road and nothing it doesn't. The dash will be a flat panel with gauges in it. I am coating all metal surfaces with a rubberized paint similar to truck bed liner.

Thanks man....That sounds good. Another coating for metal panels is POR15. It comes in gloss black, silver, grey, and clear. I used the gloss black and it shines better than anything I have ever seen. It is very hard, very glossy, and very tough. It doesn't hold up to UV light, so anything exposed to the sun will fade.
Heres two pics of my undercarraige.

Wow that is shiny. I'm kinda digging the textured look that I have going. It reminds me of rubber flooring. This is going to be more of a road warrior than a show car :)

I'm fairly sure those later model Tbirds also didn't have a HO cam, so you will have to swap it out for a HO firing pattern cam.

You will need:
mustang motor mounts (unless they changed them for the new tbirds)
HO pattern cam
5.0 fuel lines
computer
wiring harness (if pre 1991 I THINK (repeat not sure lol) you can use the 4 banger engine harness)


if your using a 5spd 4 banger car, get a 5.0 bellhousing and then a clutch & flywheel kit from autozone, as well as a clutch fork and the special pilot bearing.

I've never used the AOD from a tbird in the swap, so I have no clue on how to do that.


personally I went with headers (the Tbird manifolds blow!) and an electric fan to start with, and had a new 3G alternator laying around so I slap it on there also.

I thought there was a 5.0 HO available in the T-bird/Cougar/Mark VII cars as an option? I could swear i've seen them though somewhat rare when picking through the JY. Are those similar to our Mustang engine? There was a thread about the similarities between the engines awhile ago but I lost track of it.

This is a HO 5.0. It has the HO Badge on the intake and I have confirmed with people on the T-bird forum that it is in fact HO.
