my friend has a 93 firebird formula 6-speed LT1, limited slip, disc brakes, and he is wondering what gears came stock with the car. does anyone here know?I told him he has a 3.43, but he thinks it's 3.73.

probly 2.73's or 3.23's, at MOST 3.42's

 

in 93 it was 2.73 and 3.23 for 6 speed models. 2.73 was later in the year canceled for the 6 speed for obvious reasons. likely he has the 3.23. 94 and later 3.42 was standard on 6 speed models.
