Someone can correct me if I'm wrong, but I believe that the 3.8 tranny will bolt up to your 5.0.

However, the 3.8 transmissions are not as robust as the 5.0 transmissions and will have a shorter life expectancy behind said 5.0.

Yes, the 3.8/5.0 bolt pattern is the same.

will the 3.8 trans be at least strong enough to take the power assuming its in good condition?

If your motor is stock, it will work, but not for very long. If you're only paying $75 for it, then I say put it in there and see how long you get out of it. I wouldn't expect much more than 15K miles though before it dies. It would work long enough for you to find a used 5.0 or SC AOD, or to save up for a rebuilt trans, but that's about all I would count on it for.

This question is very hypothetical. The transmission may survive with a driver that doesn't beat on it. With a person that drives hard the 5.0 transmission could be destroyed quickly as well.

Not sure of all the exact details, but something about fewer clutches in the 3.8 trans, and I think there is a weaker OD servo or something like that. Basically what it comes down to is ford was able to save a few bucks per unit by making it not as strong, so if the trans was going behind a motor that only made 140hp, they didn't need it to be as strong as the one going behind the 200hp motor. If you do use the 3.8 trans, go very easy on it, and don't expect it to last very long. You might get lucky and have it last a long time, or it might be toast within 5K miles.

I broked a 5.0 trans.

3.8 has less clutch material I was told, and the mustang trans has more clutch material.
