Torque converters and Cams

For my summer mod im debating between a torque converter or cams. This will probably be my last mod besides a 75 shot next summer. I dont know much about these two mods, so help you guys could give me would be great. Which cams/ converter would be best for my set up, keeping in mind that Ill be getting nitrous next summer. Also which company should I go with and where can I get the best price. My car is an auto and daily driver. Thanks

Well this turned out to be a great thread. But Ill try again anyways. But Ive changed my mind since that last post. Ive decided to get bbk lt's with a o/r h this summer and maybe cams next summer. Any suggestions on cams? Also Im thinking about a 6 speed tranny sometime in the future, anyone have any suggestions for both of these mods?
