I think all the cam are made from comp cams blanks.
3800performance is that website is still around and ZZP Performance sells after market camshafts.
Personally I'd just run the stock cam and drop pulley sizes to increase boost and power. Maybe I'm just cheap though.
You'll also likely need some larger fuel injectors depending on power output. If you do indeed add a camshaft you'll want some larger injectors. The factory 33 or 36lbs ( I forget) don't go much past a 3.3 pulley range.
