Does anyone know what gear ratio usually came in a 1986 Silverado short bed with a 305 engine and turbo 350 trans?

Thanks

No. California
The word " usually " doesn't really come into play when you are talking about GM gear ratios. From your description I'm questioning the transmission,if memory serves me right the 86 c10/k10 used the 700r4. If I were to guess if it's 2wd i would say 3:42 it it's 4wd 3:73 . I worked for a Chevrolet parts dept. For 35 years, so this is a simi - informed guess.
