^^ That's correct, the bell housing is different.
I was thinking if you used the right bell housing the driveshaft will work??? I might be wrong.


Most of us just want to make sure you understand what you are getting into. SOOOOO many people get in here wanting to swap a 302 because they think it's a more powerful motor - and the truth is, stock for stock, you're equal and losing money on the swap. There are cheaper and easier ways to make power than a V8 swap.

The only 5.0 motors that will work in a Mustang are Mustang 5.0L motors. The 94/95 Motor would be the best option as it's already made to bolt in to the Sn-95 body. The thunder bird, lincoln, explorer, and F series 5.0s are the same motor but everything else is different and not compatible with the Mustang layout.

The 5.0 will not bolt up to the V6 T-5 trasmission without modification to the driveshaft. The 5.0 uses a world class transmission instead of the weaker standard T-5. The 94/95 Sn 95 platforms have a slightly longer input shaft than the older 93 and back 5.0s so again you need the 94/95 layout or modification of the driveshaft.


If you have all the money in the world then don't do it cheap and DO NOT USE a 5.0!!! The amount of money needed to perform the swap, as nothing on a 96+ Mustang is compatable with an older 5.0, then put a Terminator motor in the car. A place on ebay sells the entire swap kit for $10,000 dollars. All you need to do is install it.

BTW take it from somebody with a 5.0, the 4.6L 3V or 4V modular motor is the better building block IMO. The 2V isn't nearly as good and in that case the 5.0 is the better engine. You could even consider putting in the new modular 5.0 engine in your car. Several sites sell most of the coversion kit needed to put it in any year Mustang. That way you'd have a 400+ hp 5.0 that still can get 24-26 mpg. No older 5.0 is capable of that.

But if you insist here is exactly what you need, no ands, its, or butts about it:

or the better option:

Plus a sh*t ton of little parts I didn't get in like the radiator, shocks, struts, odd and in dash parts, etc...

Wow.... Really? Are you actually serious? You must have built that 5.0 completely bass-ackwards if you think the 4.6 is a better building block. The only thing the 4.6 has on the old 5.0 is stock for stock more power. Just the fact that cams for a 4v are $1200 should be all the evidence you need to prove your opinion wrong.

Now don't get me wrong, I'm not saying the 5.0 is the cats meow or anything, but it's certainly better than a 4.6.

FWIW: 99-04 V6s used WC T5s.

This thread....*facepalm* is all I'm going to say.

Don't get me wrong, I'm doing a V8 swap myself in my 95, but seriously? Why do you think I haven't started a thread on it myself? Nothing but arguments, different opinions, and a lot of frustration.

The V6s use a completely different T-5 than the 5.0s they use the standard T-5 transmission which is rated at 265 ft lbs of torque. The higher WC transmissions are rated between 300-340 ft lbs depending on the model.

I still personally think the 3V and 4V 4.6Ls are the better building block. The 5.0 has a lot of weak spots, and have to take extra work to keep them running past 500 hp, the 4Vs have no problem with this as long as the proper internals (such as those in the Terminators) are used. The only upside to the 5.0 is the price of being able to mod them. But other than that they are a complete pain in the *** because of the limitations with tuning and the mountain high cost that comes with tuning them. They're pretty easy to get to 250-300 rwhp, but beyond that they get costly, and generally requires F/I which pushes the block to its limits. The other down side is the age of the cars they come in, while cheap to repair they are harder to work on at times because they have so few reliable electronics.

My 5.0 works fine and the only mistake I ever made with it was running 11 PSI with a Kenne Bell supercharger, but the age of the car is taking its tole and it's about on par or even a little less than my 08 GT.

Like I said, I like the ease of working on them, but 5.0s are truely a pain in the butt at times.

because someone who actually knows what they are doing to do the swap doesnt need to start a thread about it?

with the exception of the termi motors, your not getting more then 450 ponies out of a 4.6 OR a 5.0 without upgrades
