install a non cc distributor, different intake, fuel lines+regulator and some minor stuff like throttle linkage etc.

If your going to further modify your engine, it may ease tunability. But the carb alone might net +10-15 hp(maybe) and will likely give you less fuel econ.

 

Brand new parts (assuming non-cc)

Carb $300, Intake $150, FPR $90, TC Lockup $90, HEI Dizzy & Coil $175 Misc $150

(Misc includes carb studs, gaskets, sealants, tranny fluid, vacuum lines, throttle brackets/linkage, fuel lines, etc. - all the $10 you-to-death goodies)

Almost $1000 total - No wonder I'm broke!

 

There is a tech article on this board on exactly how to do it. Follow it's instructions. I did it to my 92 RS when I dropped a mild 350 carbureted motor into it. For me it was definitely worth it- I run mid-low 13s with the new motor. If you're just tearing off the TBI system to replace it with a carb, no other changes, it might not be what you want to do.

What are your goals? Why are you considering it to begin with?
