I would personally just rebuild the 5.0. I'm definately not a fan of the early 4.6s....

but it looks like you got everything you would need to get it working, I'm just wondering what kind of little details you would be missing on from the 97?? Like dash monitoring wiring, etc..?

I would like to do something similar, I just bought a 82 mark vi and want to swap a newer 5.0 in it.

In one word no the 5.0 and the 4.6 have differant motor mounts and I belive bolt patterns. I think the flexplate is differant also
you can pick up a good running 5.0 motor used for $300 to $500 dollars
