All this talk about cams......

So I'm really starting to think I need to put a cam in my 2wd Blazer project! But here's my issue. I'm not sure where to start on going about picking the right one. I've done many engine swaps and more LS swaps than I can seem to remember, but I've never been inside of any of them. I understand the basics of cam specs, but don't have any experience on how to pick the best one for my application. My engine is a 2006 LQ4/4l80e with about 110k on it. I have a 3:73 rear gear and will most likely be going with a set of Doug Thorley headers. I would also like to keep the torque converter that's in the transmission right now, so is this possible, or will I really be hindering myself with it? Anyone with any recommendations on a cam brand and/or specs?
