Just another option to think about - there are lots of auto-salvage 5.0's out there (kids like to wreck these). I lean towards doing this myself over buying a reman (definitely with transmissions) especially if I'm not looking for a significant upgrade / race motor. I checked car-part.com (a nationwide junkyard inventory, not a site I'm shilling for) and see lots of used engines, many with significantly less than 100k miles, for the $500-$600 range.
Of course there's risk involved, you can wind up with a lemon with typically a short (30/60/90-day) warranty to return it. If you're installing it yourself, maybe no big deal. If you're paying a shop, probably a pretty big deal. Definitely makes sense to check compression if possible, bore-scope the cylinders with a cheap camera to check wear-ridges and corrosion, check the oil (if it has oil) for contamination or metal particles, change the gaskets you can reach before installing (front and rear main seals, oil pan gasket) and generally be cautious. If it runs / starts and isn't open to the elements, that may be your best bet.
I like the used route over a budget reman for a couple of reasons. Ford built these motors well, especially back in the 90's before it all moved to Mexico or China. The rebuilder may not build them so well, and will certainly be using the least-expensive Chinesium replacement parts (rings / bearings / etc.) they can install. Ones with a decent warranty (>1 year or 12k miles) will cost you. Often more than a good-running, clean '95 SN95 5.0 will sell-for. And if the rest of the car is high-mileage, I tend not to worry about putting a lower-miles used engine into it.
Just something to think about, though the gentlemen above give you some great options to look into if the rebuilt engine is more up your alley.
