I believe the gear ratios were really different between the 2.8 and the 5.0 for any year.
Check the bottom of the equations page on the home page of tgo for your transmission and the transmission from the car you got the engine from.

The bell housing will not bolt to a V8. So no, you'll have to find the V8 stuff, the 6-cyl stuff won't work.
