throttle body size question... What is the diameter of the inlet on a stock LS1 throttle body? I am trying to retrofit it to another car and want to make a CAI for it. Somewhere around 3.5" maybe? Thanks.

Interior dimension is
75mm=2.9528inches
Exterior I would do 3" rubber and stretch it around.
3.5 inches=88.9mm so it is quite a bit bigger and you may not get a tight seal
