Ive seen a few people swap in Terminator engines/drivetrains into S197s and its definitely badass!
I was watching drifting on SPEED and a some guy there did the swap and threw on a whipple for good measure LOL

Mooneyb, If you do swap in a SWEET 428, post it up here, even if the naysayers are giving you a hard time now. Not everyone here thinks the 4.6 MOD motor is the end-all-be-all Ford motor. If I can afford it, one day, I'd love to swap in a nicely built, stroked Windsor into a S197 body. John

Throw it my way!
MAN, if you want to throw thousands of dollars away, just throw it my way.
Take it from a guy who has planted engines into cars they never came in. Your idea although slightly romantic, is a GIGANTIC waste of time and money that will never be worth the effort in the end.
The specialty parts and pieces will nickel dime and dollar you to death. Have you priced a 428CJ engine? Dollar for dollar you will end up spending a whole lot more for each horsepower with the old 40+ year old 428 than you ever would with the 4.6.
Besides, It will never be street legal, or pass emissions testing.
Unless you absolutely love the process don't do it.

Lol i know it sounds crazy. But i've got to thinking lately, do I really wanna spend 4500+ on a blower and the cost of install or should I just wait till my warranty expires and rip out the 4.6 and swap it for a 428. I could sell the 4.6 and put it towards the 428, but how hard do you all think it would be to do? but dear god could you imagine how sweet it would be ...

Take your motor and tyranny and sell it on Craigs list or Ebay to help pay for the cost of a new motor and tyranny. What would make more power a 4.6 with a blower or a 428 crate motor with a blower? My point is that in the future if you chose to put a turbo or blower on, it would still make more power than a 4.6. It would weigh more than a 4.6 but if it’s something you want to do, just do it. Post video after it’s done.

I think that's cool, but just not cost effective for me. I'm gonna throw some forged guts in my puny 4.6 and then turn up the wick on my Whipple and call it a day.
For those that have the money to undertake such a venture - more power to you.

Heh, why even waste time with the stock heads, if you can find a good FE block, just go with the aftermarket heads (should have hardened seats installed already along with modern chambers).
I suspect an aluminum headed 428 would probably alot lighter than the GT500 mill, so all the stuff is there to beef up the suspension, not to mention some things like radiators and fans to cool the engine. Likewise for the chassis, I didn't take a look at the year Mustang you have, but figure the 07+ cars are good for 600hp and 500 ft/lbs+ of torque (dunno aobut earlier cars)
The legality of it would go right out the window, so no use dwelling on that and wasting money on it.
Check aftermarket accsesory drives for the engine, there might be something to mount the P/S and AC without having to get all crazy on a multi-axis milling machine. Figure on custom exhaust manifolds/headers at the very least along with a cutome x/h pipe and if its putting out some big honk'n power then full custom exaust. Interfacng the dash electronics will likely be a real ***** since I would hazard a guess this engine will not be DIS/Injected.
Transmission choices are wide open since the various M5/M6 Tremec transmissions have been fitted, just need to figure out how to make the hydraulic clutch work.
Then there is the throttle pedal issue.
While the engine might be cheaper to build (as in long block) all the rest of the stuff is gonna soak up a ton of cash to do it correctly.
Personally I'd tinker with the idea of a 3v V10 swap, its 410 cubic inches and should make a few things easier. Only downside I think would be the injector/DIS management and a proper intake manifold. The 3v heads on a V10 could theoretically support 600hp in a max effort engine.

You're not crazy, I've also thought about doing something similar to this for a long time, I'm just lacking the motivation ..
the description on that video you posted says 460ci crate engine...that's one of my
favorite vids.
I did come across a really good article with some insight on the swap,it's an 05 GT with an Aluminum 427ci cammer($$$$) that weighs less than 281ci. some of you old timers in here might enjoy this article.

I also found a 600 HP 6.0L aluminum DOHC modular CRATE ENGINE. I wrote to SHM but they haven't gotten back to me yet.

I know that for some of you guys it doesn't make sense, I guess the only way is to just drive a high Hp NA stang to understand why some of us go this route.

someone on another forum I frequent wants to try this too. IMO, start with a V6 S197, lower initial cost and you'll end up removing a lot of parts to fit that big block anyway. plus, all the other supporting parts in the drive train will need to be beefed up or fabbed for your application (like a 9in. rear axle, driveshaft, etc.).

Here ya go!!

If the link doesn't work, its for a built 428, made from a bored out 390, with a buy-it-now price of $4995, making 450 hp/490 tq on premium unleaded (or leaded). I'd buy up a used or lightly damaged V6, strip the drivetrain, bolt in a 9" rear from Currie, built C-6, TKO 600 or Jerico 4-speed, and fuel-inject the beast!!

There's also been a V-12 Aston Martin engine swapped into a S197, and the worst swap that I've heard is project Heretic, a LSX engine in a S197.

DO IT!!!!
Sure, maybe the 4.6L is just as good, but honestly, what is more impressive? A blown 4.6L, or a freaking 428
No disrespect meant to you guys with blowerwhine under your S197 hoods, but you have got to admit it has a wow factor. Its not for everybody, thats for sure. But it will give the car a different kind of appeal than a SC 4.6L has.
Dare to be different

I totally 100% agree with you Arin. It isn't for everybody, and it may not be the absolute best bang for the buck, but that's ok with me. I personally would go with a 460 crate motor from Ford. You can't beat it for sheer torque and $$. Sure it's a fat heavy pig of an engine, but good lord the sound coming from those pipes is belted straight from the angels in my opinion. No, and I absolutely mean NO 4.6L will ever sound like a big block 460, no matter how many turbos and blowers you put on it. The sound alone of that heavenly chorus is worth mucho dinero if you ask me.
