Throttlebody & K&N FIPK

I was wondering what size is the stock throttle body on an 99 z28, I know they sale 80mm aftermarket ones? Also I was wondering if anyone has the K&N fuel injection performance kit and if they like it, Im looking in to getting it? and if you do have one and have pics of it could you email some to me? Thanks.
