Is the motor going into another Stang? Will it see higher rpm ranges or be street driven? Like you mentioned before you are going to need an intake manifold and carb. Also a mechanical fuel pump and possibly a regulator and maybe a distributor with a vacuum advance, but I'm not 100% certain on that one. There are tons of manifold/carb combos out there. If it's going to be street driven and it's a basic bolt on motor a nice dual plane Edelbrock Victor manifold and a 650 cfm carb should do the trick. Really we need more info on how built this motor is going to be to make the best suggestions. Also, if this engine is going into another Stang that was fuel injected, the fuel system itself from the tank forward will need some work. Also try doing a search. I'm sure there's tons of info on here about converting to carb.
