2002 LS1 has 241s on it which flow something like 230 cfm i believe. So 230x2 is 460 so say roughly 500cfm right? I'm just guesing really.

the stock throttle bodies usually are in the 750-800 cfm range with normal pressure drops and flow procedures; higher if you accept larger pressure drops. In other words, you can almost make them flow whatever depending on how you test them, but the above cfm should be close.
I would want a filter that was larger flow just so it's not a restriction, larger the better as long as it fits where you're mounting it.
