I put a '96 engine in my '01 when I hydro-locked mine, change all sensors, get a 'pre-2000 header an down pipe, add a O2 bung up-stream, and another one down stream. Engine breaths better, runs great. You do have to pull distributor and put the late model cam sensor in it's place, but that can be set up with a toothpick. Works out great.
