Default early C4 Air box/intake performance

Just wondering what you other guys are doing with the stock early c4 aribox. I ported mine out in the throat area, and have a kN, and cut lid, and fresh air from the liscence plate. I also don't have a MAF....SD conversion. What kind of CFM does the stock air box flow?????? ideas for high flow intake????

I doubt if any NA engine here can use more air than a K&N+cut lid can really provide.

Does anybody know the CFM rating on our stock boxes?? I know my brother's LS1 Ram Air Trans Am is sick. I just put a SLP and KN intake set up on it....mother of god.. my whole hand and arm fit through the air box!! The opening is like 4" or some crazy shizil. I'd like a set up for the L98 like that!

I use a TPiS air box. it seems to be less restrictive then the Stock piece.
