A lot of foxbodys end up with crate engines in them is what I've heard. I pulled a fuel injected 5.0 out of an 87 GT... according to a few people I've talked to, that engine doesn't belong in that car... in 87 they were still carbed. I don't know a lot about mustangs, but I do know that crate swaps/new swaps are pretty commonly done in them. Check out www.mustangforums.com for a bunch of really helpful peeps in the mustang scene.
