I'd be more interested in how you managed 600 hp out of the 3800 and kept it alive.

 

There are several project threads that go into detail about the swap. The are so many different ways to approach the swap there is no good guide out there. You should check with your local inspection mechanic to find out what needs to work and what does not. The 98 has a body control module so you will need to rewire most of the car.
