I just picked up a 2000 Silverado and was curious of the stock gearing on these. It's a 5.3L FWIW. Thanks!

is it 4x4? if so you probably have 3.73s otherwise if 2wd its either 3.23 or 3.42. you can look up the vin numbers and find out or check the glovebox codes, try searching for some threads about it
