Motor Swap questions 88 cougar to 84 stang

[5.0 Fiend]

The only thing that I did to my 84 motor was I threw a rod threw the oil pan, (as far as I can see), it still ran on the other cylinders, but it was leaking oil like it was going outta style. I just plan on gettin something decent from a junk yard, because in the meantime I want to build up my 84 block with a good set of heads, roller rockers, cam, barry grant carb, and maybe even a 306, 331, or 347 kit, who knows. I am more of a carb guy, I dont want efi for my play vehicles,(it would be alright if I had a truck or passenger car), I guess I like the way it looks with the old style clamp on filter right in the middle of the engine, kinda gives it an old school muscle car look. P.S, I'm also not a wiring genius.
