throttle body size?

From SVTPerformance.com:
I did some measuring today on a stock TB.
I did not have calipers so I'm sure these could be slightly off; consider them approximations.
Stock TB Blades - 57.1500 mm (each) [2 1/4"]
Space in between blades - 7.9375 mm [5/16"]
Total size of stock opening - 122.2375 mm [4 13/16"]
