Upper Intake throttle body inlet

[Mika]

I have questions about upper intake throttle body inlet, if thats what it's called. I'm thinking about an aftermarket intake and was wondering what is the throttle body inlet size for the gt-40, cobra, and stock gt intake. I see the TRick flow has a 75mm inlet, BBK and Eldebrok have a 70mm, and couldn't find holley. Am I missing anything? Any suggestions. I'm just thinking about future boost applications.

Thanks
Mika

60 or 65mm i believe

It's a 70mm opening on the intake for all GT40 uppers. At least the tubular Lightning and the 94-95 Cobra uppers are definitely 70mm. Stock GT has a 60mm opening. (It's closer to 58mm)

Whould I gain anything by porting my stock gt upper to 70mm my plans are to at least get a gt40 soon but for right now I work at a macine shop I have access to a lot of machinery
