Does the 4.0 liter v6 mustang have the same transmission as the 4.6 liter v8? If so does the bell housing have the same bolt pattern and torque converter?

JCON

the automatics are the same, the manuals are not. Since you are saying torque convertor I assume you have an automatic. Not sure about bell housing, have to leave that to one of the several members who have done the swap. There's a lot more than just an engien and transmission with a swap. you need all accompanying electronics and you need to beef up your suspension and brakes.

While they are both 5r55s automatics they aren't exactly the same from what I understand. The torque converters are different and the input shafts are different

I've also heard the valve bodies were different?

Cheaper to trade for a GT than try to upgrade a 4.0 to a 4.6

Yep, the input shaft ordeal screw the pooch on swapping those trannies.

How do you figure? Cameron (the guy I bought the blower from) had 144k on a 2005 that was paid for... He paid around 2500-3000 for a V8 swap w/ 30k miles. I think thats cheaper then selling what he had or trading it in.... RIGHT?

Depends on how you look at it. Huge difference between a car with 30k on the body and motor and a car with 30k on the motor but 144k on the body.

Did the 2500-3000 include swapping for bigger brakes and other gt components that would be ideal if not necessary?

He already had an 8.8 and the other components, but the question was a V6 to V8 swap which is just a motor. Right?

It isn't extremely hard to find a V6 and equivalent same year GT in an '05, '06 or '07 with a $2k - $3k price spread. Even if you could find the engine, tranny, rear, electronics and suspension parts for $3k (which would be a bargain) you have one heck of a lot of work to do.
