The stock throttle plate size is 75mm, the smallest part of the openingis 70mm. Most ported throttle bodies are 75mm throttle plates and 75mm at the smallest part. The BBK 80mm have a throttle plate that size and I am not sure what the minimum size is.

Flow for a stock is around 600cfm, a good ported one is 720cfm+ and a 80mm hole should support 800cfm, but that's only a guess and buy the performance I've seen from the BBK it's not that good. A good ported one is good for 500-450 hp.
