Default throttle body hole....how big is stock?

not sure if this is internal or external....but anyway

i currently have a ported stock TB on my car, i beleive the hole in it was enlarged a little bit by my cam installer who also tuned it.


i'm considering picking up a FAST setup, so i want to know how "usefull" the TB will be to sell afterwards.

i suppose worse case i could have a shop weld up the hold, and i can redrill the factory size.


soo...

what's the air hole size in a stock ls1 throttle body?? not the bore diameter...the small hole in the blade...
