There were two V8s available in '82.
If you ordered an automatic transmission (C5) in '82, the only V8 you could get was the 255/4.2L.
If you ordered a manual transmission (SROD) in '82, the only V8 you could get was the 302/5.0L.

When I had my Pinto Cruising wagon, I entertained the idea of building a 260 for it. I thought it would be so cool to drive a small, gas sipping V-8 that could produce a nice exhaust note, that almost all 302 parts would fit, and that could propel that little car as fast as I would ever want to go. I then ran into the 5 bolt as opposed to the 6 bolt bell housing problem. So, I explored the 255 option. From what I learned about the 255, I'd have been way better off putting a Chevy 265 in there, and just close my eyes when the hood was open.
I still think the idea of a turbocharged 221 is cool.
short stroke (260) and tiny bore (255)
someone do it
The 221, 260, and 289 all share the same stroke.
221 has a bore of 3.5"
260 has a bore of 3.8"
289 has a bore of 4"
221-260-289 all have a stroke of 2.87"
255 has a bore of 3.68", and a stroke of 3"
If you REALLY want short stroke and short bore, get a 221. Be warned that only 221 heads will work and they're pretty rare beasts. Parts are plentiful, since all 289 and 302 parts will fit, besides cylinder heads (must keep stock valve size, since bigger 260 or 289 valves won't clear cylinder walls).

Earlier someone mentioned an article in Hot Rod but this is the one in Car and Driver that I remember from back in the day when i built my 302 Capri.
