Default Stock throttle body sizes
I have a 97 with a BBK 80mm TB. Just bought an LS6 intake. Just wondering if my BBK will fit. What sizes are the stock throttle body's through the years? TIA for any help.

As far as I know all C5s have a 78mm TB. LS1 or 6.

If the BBK fits on your current LS1 manifold, it should fit on the LS6
