Boosted Falcon

Hey guys!
I'm looking at buying a car with a 221 super persuit 6 cylinder engine, but I'm wondering what the most performance based carby that I could put on it would be? Any suggestions to other performance type modifications that I could do?
Thanks
Cam

What intake does it have mate? (Original 1V type, or 2V retrofit?)
Regardless of the answer, the stock ones are fine for a std motor!
