    3.08 had to have been the most common for the stock, next most common was 2.70 or something like that a iduno

    You could have 3.08, 3.42, or 3.73 gears from the factory. With the advent of the overdrive transmission (if it is an automatic) and fuel injected engines, it seems as if most of the late '80's to early '90's Blazers had either the 3.42's or 3.73's.

    What would a 10-bolt from '83 have stock?

    Well.......I would say you had about an equal chance of having 2.73, 3.08, 3.42, or 3.73 gears.

    I have 2.73's in my 89 K5. Whose idea were 2.73's? Pity me.
    As undesireable as this ratio is, don't rule it out. I'm running 32X11.50X15 BFG muds, and I just spent $1450 on a complete rear-end rebuild. Hope you don't have 2.73's my friend.

    I have `89 K5 Silverado with a 12 bolt rear axle 2.73 gear and 32x12.5/15 tires and this is not a good gear setup i`m driving 75 mph by 1450 rpm. i think 3.42 or 3.73 are the right ones for me.
