One of the engine options in 96 for the T Bird was the 4.6, so you could swap one of those into yours, or even a 5.0. However, the question is, does this swap make financial sense? By the time you find a suitable donor and swap out all the mechanicals and electronics, you would be way further ahead selling yours and finding one already with the V8 from the factory.

These cars aren't like when we were putting Olds engines into 50 Fords, there are so many emission systems, computers, and other things that to make all of those work takes a lot of time and money. The game has changed with all the new advancements.

Just my opinion.
