TOTAL DRIVETRAIN SWAP FROM NEW STANG

Nemesis67 · Feb 22, 2007

OK. I now this has been asked before, so sorry guys if it seems to be a repeat question.
I know Reenmachine has had plenty of experience so he might be the best source. But everyone's input is welcome.
I'm contemplating buying a wrecked mustang and swapping in the entire drivetrain: Engine, Tranny, Rearend. Plus brakes and some suspension pieces if allowable. Basically anything that will be usable and seems cool, to me anyway, into my 67 Fastback. This seems to be more economical than buying all these parts piece by piece. And I get fuel injection with harnesses and a computer. I'm looking at all GT's between the years of 95 to 2006.
Now, which years would be the best candidates? And how hard is it to swap a 4.6 into a 67 engine bay and the transmission under the tunnel? Plus, what will I be able to use off any of these candidates? Any and all info in this area will be greatly appreciated. I'm doing the research before I actually purchase a donor.

Swapping a 4.6L into a 67 is not that hard with a donor. You will need the transmission and motor mounts which are available through DVS restorations. The SOHC will fit, but it's recommended to notch the shock towers for more clearance. The DOHC fits, but requires notched towers, but you are still able to retain stock suspension. The front oil pan will need to be swapped out with a front sump, and pickup, which you can get directly from a Ford dealer or Canton. The oil filter needs to be relocated, I've heard people using relocation kits from Canton. Of course, you'll need a thinner profile radiator and fan. Theres tons of little things that I cant remember, like PATS, which will have to be disabled.

A 94-95 5.0L swap would be the most common, cost effective and easiest. It's basically a swap, bolt up deal, of course with a new or modified harness which are available online.

I don't really know about 05+ yet, I haven't completely researched those years yet. Suspension you will not be able to really utilize, I would recommend selling it to fund your project. You will be able to adapt the brakes from a SN95 with an adapter bracket, I can't remember the seller off hand though.

Yeah the 4.6L, I'm the wrong person to ask about that because I really don't like that engine. The brakes though I think there are a few different sources out there for conversion parts so you could swap over to the newer larger brakes Like from this dude http://www.mustangsteve.com/cobrabrakes.html

After dealing with a 390 and a 427 in a 67 Stang, I don't see why anyone would want to try and shoehorn a physically larger, but displacmently smaller engine in one. The 3v motor is completely electronic and from what I've seen, integrated into the wiring harness, so I doubt you'd be able to separate the harness from the car, without taking the whole harness. Yea, it runs great for it's size, but a well built 5.0 stroker or even a 351W stroker can be built cheaper and with more power.

Bit its different, think of the wow factor!

Going with a 5.0 swap donnor would be alot easier, and cheaper. Not to mention better aftermarket parts availability, etc.

Personally, I like the word 'displacemently'. :SNSign:

yeah, it struck me too. I think the only reason for a mod motor is the 'wow factor'. too much effort and cash for the seat of the pants factor. However, they can be stroked to a whopping 5.0L.

Nemesis67 · Feb 23, 2007

Yeah, I'm not looking for a wow factor here. I'm just trying to do the easiest and cheapest swap with modern technology. I thought about a 04 Mach I swap, but I needed more input from the ones who know, kind of a "look before you leap" factor. I've also considered a 351W efi from a 94 - 96 pickup or bronco. All I could really use from those sources would be the motor, harness, and tranny (with different gearing). But I am trying to get the most peices for the money.
INPUTS ANYONE??

Did I just invent a new word? I couldn't come up with one off the top of my head that decribed what I was thinking in fewer words.:SNSign: Maybe it should have been spelled "displacementally" .

Roller 351W. Block casting number F4TE is what you're looking for. But I don't think you'll want the transmission to go with it. E4OD's were the transmission of choice behind the 351W's in 94-97. Damn good tough transmission, but it's huge and hold damn near 4 GALLONS of fluid. A manual behind one would either be an M5R2 or a ZF 5 speed. Eitherway, these are also big transmissions.

You also have the option to carb the 4.6L too.

mattrod70 · Feb 23, 2007

ya the carbed hurricane 302 modular was badass at sema last year.

I want to go EFI. No carb.
The 351W was my original plan. I guess getting a wrecked donor mustang with an EFI 302 would be the best. Let's say a 94 - 95, that would also give me some front suspension (coil over strut conversion) and brake parts. I then could drop in the 351 and use the 302's wiring harness and computer to get the ball rolling and eventually get the computer reprogrammed to support the stroked 351. Does this sound like a solid plan to you guys or am I just going in the wrong direction?

You could stroke the 302. EFI parts are cheaper and easier to find for the 302 than they are for the 351w since our beloved Ford Mo. Co. didn't do high output 351w engines in any volume. You'll have to decide whether you want to go auto or manual with the tranny. The T5 you'd find in a donor GT will need to be upgraded or babied, but you could upgrade to stronger T5 internals for not a whole lot of dough.

Is the coilover strut conversion an improvement over the upper/lower control arm set up we've got on our mustangs?

boost is displacement's replacement!

i say go for it. if you can find a 32v cobra motor youll be doing good, a 03/04 cobra would be best. i also like the 3v with its intake design.

James Kirk · Feb 24, 2007

Keep in mind if you're concidering an older doner 94ish you are getting 12 year old used parts. I built a Factory 5 Cobra that way and over the course of 2 years of driving I had to replace almost everything. Depends on what your goal is but I can assure you you'll replace it, "a part" now or later that much is certain.

Only thing wrong with the 3V motor is it's so G-Damned ugly. I think Ford modeled it on the Powerstroke diesels. I'm ashamed to pop the hood on my 06 GT.
