If you're going to do a swap, use a newer 5.0, 87-92 have forged pistons, roller cams, and better heads than the older motors. Is the car a 5 speed? What kind of shape is it in? If you want to swap it, I'll give you some pointers via PM (I've learned to keep my opinions to myself in these tech forums ) If you know you are going to get rid of it, I may be interested, and a good friend of mine may also be interested so let me know.
