What is stock throttle body size?

I thought it was 70mm, but then someone told me he was sure it was 65mm which didnt seem right for some reason. Which is it and is it worth upgrading to a 75 or 80 when i get intake, or is it fine to leave it stock?
thanks-

Stock size is 60mm

The SC's (all years) used a 60mm Throttle body. The mass air is 55 on 1989-1990 and mid 91 and late 91-95 is 70mm mass air.


Hope this helps...

Ok, thanks guys-- was just curious about that, so if i ever get intake, do i need to upgrade the MAF or TB? Will it just suck if i dont or still be decent-
Thanks a lot for the help-
