Cam, Converter, Gear?

Lookin for sugesstions for Cam, Converter & Gear. I am building a 383 and I have already aquired a TCI Breakaway Torque Converter/advertised flash 2400, new in box for $150.00, from a friend. What cam and gear can I get away with using this converter. I would like to run a 509 cam with 355 to 390 gear. What you fella's think? :toothy7:
