what is the stock size of the throttle body on a 97 LT1......isnt it 48 mm............................and if any1 knows what is the stock ize of a throttle body on a SVT contour....some kid told me some absurd size like 60 mm i was like wtf u have to be joking
thanks guys

 

i dont know for sure but 60mm is very possible stock!
you have to remember that we have a TWIN bore 48 mm throttle body meaning to bores at 48mm each
the one one the contour is more then likely a single bore throttle body like on LS1's and 5.0's for example

 

hey man thanks that really cleared everything up for me and my friend im just dumb lol
thanks
