8.8 rearend. bigger fuel pump. tranny. motor. k-member with springs and shock/struts. computer. thats all i can think of from mine.
tranny's for 4cyl and 5.0 are different. You will need the wiring harness also.
It sounds like a lot of work but it shouldnt take much. You can get a 5.0 k-member off ebay for like 50 bucks plus like 100 for shipping, or a local craigslist ad will be cheap. Youll spend a couple hundred on the front suspension parts. Couple hundred on the harness. 8.8 from a junkyard. hundred bucks for a fuel pump, and youll have a roller. Then you can buy a complete engine and a tranny for under a grand or slowly build it up on a stand for alot cheaper. I'm sure there is more stuff, I've never done the swap, I am sure someone else will add more.

I guess one of the most important thing to ask you is are you planning to run a carb or fuel injection?
You dont HAVE to change the rear axle or front suspension but it is a good idea too. The crappy 7.5 will hold up if you are not prone to burn outs. The front suspension will be ok if it isn't already wooped out, but it prob is due to age. You can get some cheap struts from O'Riley's and press on if you are on a budget. Front disc brakes from a donor 87-93 are nice but not needed. Bear in mind the 79-86 mustangs all used the same brakes for all those years and they worked fine for a 5.0. Everyone will tell you need this and that, but if you are just putting a 5.0 in and not making a race car the old stuff can survive this. The 5 speeds are diff for 4 cyl and 5.0. If you are using a carb the painless wiring harness for the duraspark ignition is awsome and cheap, about 100 bux. Since it is a 4 cyl it's wiring wont jive with what you are doing. If you are using a roller cam engine, you will need a non EFI distributer, and it will need a billet steel gear on it for the roller cam. If you are just using a non roller 5.0, just use any dist that is non efi. The painless harness just needs a power source and a duraspark box from a donor car or ebay. You don't have to change the K member if you do decide to upgrade your front suspension, they are all the same, save for the convertable. Your 4 cyl K member will work just fine if you want to upgrade your struts, springs and brakes. If you do upgrade your brakes to the 87-93, you will need a donor spindle from an 87-93.

sorry I wasnt sure about the K member. I do recommed front Suspension though. Its horrible if you have to drive it in the rain or take corners. Exhaust and the 8.8 is a must you have a 5.0 you're going to beat on it. I didn't do the converstion on mine. My cousin did I helped but not to much, I was 14 when he did it. I was into riding ATVs at the time didn't think I'd get a 5.0 as my first car so I didn't care much. But now I wish I did since I have that car. Radiator and all that stuff. A/c kit is about $700 if you want that.

bigger wheels too! Anymore questions just post them or contact me. I'll give my cousin a call if I need too. Its well worth it I know my car inside and out from having to replace parts.
