Base 1/2 ton trucks got a 3.73. Most 3 speeds were also 3.73. 3.07 was the norm for 4 speeds, although if memory serves, a 307 with a 4 speed still got the 3.73
As for the original question... 350 with an auto got 3.07 gears unless optioned in a 1/2 ton.

Most of whats been said here is acurate, although, 4.56 I don't think was ever in a 1/2 ton, 3/4 tons didn't get a 3.54 with a small block, that was a big block gear. Small blocks and inlines would get a 4.57, 4.10, or a 5.13.
