Of course it will fit, it's the same size. Will it work? Not without a lot of modification. Your '89 is a Renix motor, the '99 definitely is not so you'll have to replace most of the harness and all ECU components along with several other things that will ultimately end up costing you about the same as a crate 4.6 stroker with lots more power, torque, and reliability. It is possible, people have done it, but it's getting harder and harder to find things people haven't tried.
So, will it fit? Yes.
Is it a good idea? No.
