3.8 to 4.6 swap

Eventually I want to swap my 3.8 to a 4.6. Does anybody know what exactly I would need to have in order for me to swap a 4.6 in?

Go ask in the v6 section. They're the ones that will have done the swap and have better information.
Off the too of my head:
Motor
ECU
new harnesses
ABS module
TC module
New motor mounts
Probably new K member depending on what you have right now. I don't know what the v6 came with.
Much more that I can't think of

You need a lot of stuff. Go search it on google. Other forums have compete write ups and parts lists for the swap.

You will need a GT harness, ECM/CCRM as well as harness to ECM. 4.6L, if your going 5 spd that will be the easiest. The read end should be upped to an 8.8. are you looking 2v or 4v

K member is the same, new gt mounts, also you will need the hydroboost brake system as the power air booster will not work with the 4.6L

There would be an easier goal. There are a lot of things to that swap. But if you were to find a crashed gt it maybe the best. I know places like LKQ sell motors for 250 if you pull. But tracking everything down can get pricey. Maybe a pushrod 5.0 might work for less. There was the 99 saleen S351 it was the only 351 produced in a new edge body. With that swap you could find a 95 k member. That way the brake booster can be left alone. I would look into that if I had a V6.

I have a 98 gt engine and the pcu I can sell to you. All the engine has is a spark plug hole is stripped. Good to do a pi head swap.

If you're going to put all that work into swapping a motor, why not go for something with more power?

What he says is true but will be a lot more expensive. Im in the process of doing the swap for a coyote and is **** expensive. That is why I have the 2v and pcu available with stock kmember and steeda springs if anyone is interested.

No real point in swapping in a 2v 4.6 might as well just buy a GT at that point you can find them for 6-8k which I can assume equals or is slightly less costly then a swap depending if you do the work yourself or not.
