Coyote install in a 1973 Fastback.

[protouringstang73]

I’m thinking about doing a 5.0 coyote install in my 1973 Mustang. Has anyone done that and know what it takes? I will buy a engine and tranny together with all nessecary harness. But what else does it takes to make it possible, do I need to delete the shock towers or is it possible to install it without deleting them?

I don't think they will need to be deleted, but may need some massaging. The Ford Racing catalog says they are 28 inches wide, Hot Rod magazine says 29 inches wide. The 429 is 27 inches wide. They are about 1 inch taller than a 429.

Some things I noticed...

1) Oil sump is on the back - not the front. That would require some sort of pan / pickup swap as the steering tie rod is in the way along with the cross member.

2) I think the drivers side exhaust manifold / cat would be trying to occupy the same space as the steering box. A custom header may be needed.

If I was to do my drivetrain over again today I would think about a coyote swap too.

What is needed? For sure, money...lots of it!

Canton makes a front sump oil pan $340

Doug makes the headers $765 for ceramic coated

Chances are you won't be able to use the stock wiring harness, unless someone has figured out a way to bypass the anti-theft electronics that are built into it. You can get a control pack for under $2,000 for automatic or manual transmissions.

I think somebody already mentioned $$$

Here's a good article

Be nice to see someone do this. I thought about it, but as I get more years added on it gets harder to do the normal engine rebuilds, etc., let alone a swap like this. I've done some interesting ones in the past, like a '92 fuel injected 5.0 out of a F-150 4x4 into my older son's 1985 Bronco 2.

Good luck and please document it well, this will make a great build thread.

I'd go with an aftermarket engine management system, do a custom fuse box and splice the new engine management into the rest of the harness for lights and such. You'll also need wheel speed sensors since the speedo cable wont have anywhere to go in the trans

The easiest way to deal with the mechanical speedometer is an electronic to mechanical speedometer drive

Just another $300.

Thanks a lot Don, that’s some udefull measurements, just what I needed! And thanks for your other replies, that oilpan looks great. As for the speedometer issue, I allready got the Dakota Digital instruments waiting to be installed, so they works with the electronic sender.

Gateway Mustang has done a 71 for SEMA in 2015. They did have to notch the shock towers. The complete build is on their website.

I'm planning a coyote swap on my 71 convertible. The Gateway Mustang is a good one to reference as they squeezed it in without deleting the shock towers. There is another red convertible (72?) With a coyote squeezed between the towers. Its red with a white interior and white mach 1 stripe. Its on youtube and google but no real build thread.

I am going a different route. My plan is to buy the kit designed by Rod n Custom. It deletes the shock towers, comes with a new crossmember, control arms, coil overs. If you aren't familiar with the kit definitely check it out. I budgeted about 4 grand for that kit.

Ford makes the wiring harness and pcm so its pretty much plug and play. Power by the Hour also makes a pcm/harness kit that I believe will run a 6r80 trans. I budgeted about 2,000 for that.

I'd like to do a 6r80 auto in mine. 4r70, 4r75, will bolt to the coyote as they share the modular pattern. I think the PBH pcm will run the engine and trans, but Bauman makes controllers that will run them too. If you want a stick its much easier. The trans tunnel will most likely need to be opened up.

Nice to see someone else jump on the bandwagon with these engines. They are getting cheaper to buy, I have about $200 in my f150 5.0 after parting the truck out. Its the accessories to run it that get expensive.

I found this in Austria made by a company called RRS. They have made engine mounts and shocktowers that gives a lot more room in the enginebay, the parts are made specific for our years. They have a lot of other cool suspension parts for our years, including rack and pinion that bolts directly into the points where the original steering where installed, very cool!

We had a member doing this in a blue fastback. I think they went by Coyote or something like that. Search the listings. I also know a guy who did one in a 72 vert. Took a fair amount of frame work to get it dropped in with the steering and accessories if I recall correctly.
