I have been scouring the web to see if someone has taken one of the new Shelby 5.2L Flat Plane Crank "Voodoo" engines and transplanted them into a '64-'68 Mustang. Has anyone done this? Does this swap involve any more complexity than a standard "Coyote" swap? I'm considering this for my '67...

Not me, but that would be cool! And spendy!!

Since FP does not sell a Voodoo crate engine, so the first problem is where to get one. There are of course wrecked GT350's going to auction, however they sell for premium prices. If you have an unlimited budget, consider the 5.2L XS crate engine as it is good for 580 HP out of the crate. The $20K retail price will probably be excessive.

An alternative, I believe the Voodoo heads can be purchased and will increase the output of a regular Coyote.

The Voodoo in a vintage Mustang would be cool, but the cost factor might be a deterrent.

 

A flat-plane crank Coyote would definitely sound amazing in a classic Mustang. It might be tricky to use the factory ECU and tune if it is tied to anti theft devices in the donor car. I'd be curious to know if the Ford Performance Control Pack would be compatible with the Voodoo engine with the proper tune installed? One would pay a hefty premium for the GT350 engine. Meanwhile, other flavors of the Coyote engine are available with similar performance numbers for a lot less dough. A supercharged gen 2 or gen 3 Coyote would surpass a Voodoo in performance. However, I understand there may be no substitute to the flat-plane crank if it is music to the ears.

 

Unless you’re planning on doing substantial chassis and suspension work to harness the power of the Voodoo motor, there’s going to be no advantage over something like a common truck Coyote motor. Even that I think would overwhelm a stock chassis and suspension vintage Mustang IMO.

I’m all for a swap like this IF the rest of the car is built to the same high standards and performance. Otherwise to me it looks out of place. Not to mention a unsafe vehicle that can’t handle the power.

 

I'm on the hunt for a Voodoo engine for a customer. He wants to put it in his Pantera. They are definitely going for a premium right now. Part of the problem is making it run and there's little to no aftermarket items for it. It will be a learning experience once I get one.

I have a 5.2 voodoo with with a TR3160 6sp manual from Mars LS Swap, it's turn key with a stand alone ecu system. Asking 25k. I had to wait a year for it. Lmk if anyone is interested. It's in a crate ready to go, ad battery and a bucket of fuel and she starts up.

 

@Huskinhano - I totally agree. I was planning on improving the chassis strength/suspension/steering by fabbing in a new chassis like the RoadsterShop Spec chassis for classic Mustangs. That seems like the best way to add the needed safety and performance attributes capable of handing 500+ hp.
@classicdoug I'd love to follow that build once you start diving into it. I'm sure it will present similar challenges to what I'll face.

 

To answer your question: Yes! 69bosssvt got hold of a special
Voodoo motor and will shoehorn that beast in this VMF thread...

Both the Voodoo and the A52XS crate engine is discussed in
the above thread. I prefer the cross-plane A52XS variant due
to street-ability and mostly 'dat classic V8 exhaust sound.

Anyhow, the fast-and-easy way to get a Voodoo+ECU is to
buy a used, low mileage Shelby GT350 and then scrap it.
The slow way is to wait patiently for years until someone
wrecks a GT350 and then parts out the engine+ECU.

 

@hsvtoolfool Thanks for the heads up about that other thread!

These Voodoo engines are rare, but they don't seem to be that hard to find. I can see a couple on Ebay right now, here and here. Yes, they are as expensive as buying a brand new 5.2 Aluminator XS engine, but many of them on Ebay appear to come with all the connected components that would make troubleshooting an error code fairly straightforward. It doesn't appear that someone who have to to buy a whole car or wait years to find an engine. Am I missing something?

 

lOOKS TO BE PRETTY COMPLETE. COMES WITH PATS BYPASSED IN PCM, INTS CLUSTER, BCM, BUT I DONT SEE A FUEL PUMP CONTROL MODULE OR A GATEWAY LISTED BUT THE DLC LOOKS TO BE PART GATEWAY.
BE INTERESTING TO SEE HOW TECH SUPPORT WORKS THOUGH.

@gordonr Good point.

 

No different than installing a Coyote, everything interchanges the same.

 

Looks like everything including the gas tank.

Who couldn't love that orgasmic sound coming out your tailpipes but I would suggest folks check out this thread:

https://forums.vintage-mustang.com/...l-discussion-non-vintage-mustang/1149950-so-police-picking-hellcat-drivers.html ;o)

I have a friend with a Voodoo GT350 - heads turn at the sound everywhere we go even at idle. Its very cool, frighteningly fast - but it seems a little silly to be a "race car" with all the weighty gimmicks and gizmos like AC seats and built in exhaust tone servos for starters. I sure like the 2.5 turns lock-to-lock but he says its not very comfortable on long trips due to the steering being so responsive. He says its hard to just relax because he is always correcting and recorrecting the tiniest movements no matter what "mode" the steering is in.

BTW, I loved the video, but what put a smile on my face was with dash pack quipping repeatedly; "doors open"...

 

If you succeed, it has been nice knowing you.

 

I would love to but even though I have already blown my budget, that would be pushing it out of bounds for sure. I would even like to put new Aluminator, a cross plane 5.2 but that would add at least 6K to the cost.
Currently shooting for Gen III Coyote.

 

@BJS - Ha! Because I'll die driving the thing?

 

You will have crossed the streams! Bad things happen.

@ClassicNation: YES! :lol:

 

A cheaper way to get the flat crank is have one made for a 289-351 block. Then have a custom cam made. Imagine the sound of a 289 with a flat crank at 9000 rpm.

LOL.....I am not sure how that would benefit me in any way or what I would do with it...BUT...if I had the time and money I would do that just for the awesome factor. That would be a blast listening as I wound up through the gears.
Why don't you do it and let everyone know how it does?

 

I'm not sure the rest of a 289 would stand up to 9k... Although it would look correct and sound AMAZING!

 

I came across this website today. Looks like long blocks that are using flat plane cranks. I see SBF 8.2” and 9.2” decks with Windsor or Cleveland heads. Not sure if you can get a rotating assembly though. I emailed more info on that.

Hello everyone. Haven’t been on here in a while. I’m currently doing this swap. It’s much like doing a coyote swap. Car is my 1968 Mustang hardtop.

 

That is one beautiful sight.

Your work and car is excellent and I 2nd the need for a proper build thread!

 

I've heard that ford had to do special things to the gt350s to help cancel out harmonics/vibration because of the flat plane motor. I believe there is weights/dampness they hung on the chassis in certain locations. So keep that in mind when swapping to a different chassis.
