One thing i forgot to add, if you live in one of the more crybaby areas of the country with emission testing, a tbird 2.3T swap may not be an option, they went out of production 89ish, and most emission laws state any swapped engine has to be same year or newer then the host vehicle.
Out of curiosity, which gears are in your rear end? Rolling a 4.10 axle in place of a 3.55 or something would give you more punch outta the hole, and your clutch would thank you.
Also, if you did decide to go with a 302, dont be afraid of a carburator. Itll make swapping much eaiser. With a good choke they do just fine in the cold, and you will maybe lose 1-2mpg depending on how hard you hammer it over a EFI, and power would be more less the same assuming you use the same year engine (IE, a 95 302 with a swapped on 4bbl isnt going to lose any power over a 302 of the same year with factory EFI)
