pascal i was/still am giving that some serious though

hmmm where can i see this at?

Even if you go with the 281, the electronics will have to be replaced.
That could be costly still.

I haven't done this so my words can't wait too much.
See if you can find someone that has done the 4.0 to 4.6 swap.

Also, don't forget, all the drivetrain will have to be replaced as well, with the 4.6 swap...
Different tranny (for manual), DS, rear and brakes.

You're in for some cash regardless.

An old pushrod mill would look so good in there.
Sounds much better than the 3V engine family too.

You mean something like this one? https://www.northparkmotorsports.com...l?currency=USD
I know I already posted this link, but it warrents it, 351s have such an enormous potential, many people have gotten over 500hp N/A, God knows how much if you put a blower on it. And you can even get them with an aluminum block, which would make it lighter than the 4.6

And for the price, considering how cheap older style trannys and rear-ends are, and the lack of almost any wiring, you will get more power for less money, and have far more potental in the long run.

what else would you need if you swapped to a carbureted motor?

TAoW1939

Well, once you got it properly mounted in the bay, it would need fuel flow from the tank, and the starter would have to be wired to the key switch. A transmission that will mate to the engine, at least an 8.8 rear, if not a 9" (consider the torque these engine put out). You would need to take it to an exhaust shop and have them fab some pipes to fit to the manifolds. A custom gauge setup (possibly analog gauges). No other wiring should be needed, just getting the thing to mount up properly.

I have seen a video of a 460 swap done to a v6 s197, and read an article about a guy that swapped his 4.6 out of an old 427 Cammer (over 630hp N/A!). So it can be done.

There's always little Gizmos that are almost impossible to foresee in a custom swap.
The throttle pedal come in mind...
No fly by wire with the Windsors.
Header clearance with the steering shaft (heads on the push rod are lower).
If manual tranny... what do you do for clutch? Hydraulic, cable?
If auto, will a C6 or AOD fit in the tunnel?
If you go 9" rear, will you go with drum brakes (no way for me) or rig up discs on that.

Not a walk in the park still, but a fun built for sure.

TAoW1939

Yeah, those might need some fab work, I dont think the header clearance will be a problem considering the 351 is alot smaller than the 4.6, if they can fit the 5.4 modular in there, anything can fit.

And for the trans, If I recall from that article I read about the 427 swap, they said the shifter came straight through the console like it was factory. But the linkages would have to be worked around.

None of the seems too difficult (although I work in a shop where we retrofit and modify vehicles ranging from f150s to Firetrucks and Garbage Trucks more often then not). And considering the lack of wiring, mechanical retrofitting wont be that hard.

i dont understand the logic of swapping the engine in your car....

if you have that kind of money just sell your car and get something with a bigger engine. save the time, money, and headache

just my 2 cents

TAoW1939

You cant buy a mustang with anything bigger then the 5.4 (and those are 50k). Better to spend 10k and put something even bigger into the car you already own and love.

Imagine hopping in your current stang and turning the key, and instead of the mellow mumble of the 4.0 your hear and feel the rumble of an engine that was born for a mustang in every way.

AMoRT

alright alright i admit that would be very cool, but still i dont think i would ever do it
