Where and What to Buy?!

[99stallion]

Ok, this is kind of a dumb question but I am very indecisive; I'm just asking for opinions here. I'm going to buy a cam for my '99 V6, and more than likely ported heads/intakes. The cam has to be able to support a turbocharger and/or a 50 shot of nitrous. What would be some good cam specs (I'm not a real huge fan of all the "popcorn" in the exhaust either)? Where would be a good place to shop for these...Super Six Motorsports? Delk Performance?
Any thoughts or advice would be much apprecaited!! Thanks!

Oh, one more thing; does anybody know much about the Snow Performance Boost Coolers? What are they like?
