I need to know whats the throttle body size on LT1 Corvettes. I know LT1 equipped Z28s are running 48mm. Any inputs would be greatly appreciated.

I believe the Vette LT1/LT4 TB is also 48mm. That is more than enough size for the stock LT1/LT4 motors until you begin to do internal mods. A bigger cam and head work along with headers would need a TB in the 52mm range. Going to more displacement such as 383 cubic inches and the same mods would probably need a 58mm TB.
