I'm just didn't realize that people were gearing them like that with the cams available in the base cars. Not really surprising (that I wouldn't know it) though as I'm not really a 'numbers' guy when it comes to these cars.

It’s quite uncommon, the vast majority of GTO’s were built with the standard issue gears for the engine and trans they had. In 69 manual trans cars (350 or 366 horse) came with 3.55 gears (3.23 with AC) and automatic cars had 3.36 or 3.55.

Of the cars ordered with stiffer gearing almost all are 4 speed cars. Very few automatic car were ordered with optional gears.
