Exactly. Getting the parts is half the journey (challenge, fun, whatever you call it..it can take time to find what you need, even if it's all in one car). Pulling out the V6 drivetrain and putting in a V8, it's very very very satisfying, when it all comes together and fires up and vrrrroooooom!
This is, IMO, for the person who can do the work mostly themselves with some help, who does not have to pay labor to do the work. If you had to pay labor, it'd make it pretty-much a no-brainer to not do it all, but trade for a GT. It does take a lot of effort, and if you dont have the ability or knowledge to be able to do all the things needed, including the on-the-fly ingenuity needed to solve issues that come up, then trying a swap is not a good idea.
But, for those of us who have done it, or are inspired to do it: to those of you who have not done something like this or have a GT to begin with, you have no f'ing idea wtf you're talking about, so don't bad-mouth those considering it...just go away!
Regarding 'insurance' concerns, yes you're perhaps taking things at a little more risk, depending on your coverage, state, local laws, etc. Any locale enforcing VIN # matching to drivetrain components would make a swap much more risky, from registration and insurance perspectives. Yes, you you total out your car, your car wont get as much value as a GT, but is that going to hold you back? Not likely.
Well, this all said, IMO though, Mustang's SHOULD have a V8. But sometimes you've got to go with what you have or can get, and a V6 is better than no Mustang at all. Then there are those who's car was never intended to be modded, or made into a V8, and was bought for transportation as a V6 vehicle with decent MPG capabilities...until that all went out the window.
Good luck, future v6-to-v8 swappers!

Sorry to reopen this thread...
I am in a similar boat. Can get a V6 auto transmission for a VERY low price... my V8 has the 1-2 and 2-3 flare ups... Could I get the V6 transmission, put the V8 bell housing on it and the input shaft I have and drop it in my engine? Would that work?

No. The cases are different. Unlike other trans, the 5r case does not have a separate front-half bell housing.
You could get a v6, use many of the internal components a rebuild the v8; but for the effort and price, you might as well get a new overhaul kit for the v8 and put all new clutch packs and all in it, rebuild it right.
But it's up to you.
(I looked into doing something like this as well, as I almost picked up an older v6 with auto and was going to put in a v8 drivetrain and rebuild a broken v8 5r55s with the v6 internals. Made more sense to just find a good used v8 5r55s or do a rebuild with new and better parts.)

I ended up finding a V8 trans with not too many miles for an OK price. I intend to give it new TCI servo pins, do the servo pin TSB and give it a new filter and fluid. Should be a good transmission after that
