Really depends on the gearing. 1/2 ton V6 GMC's came standard with 3.07's. Incorrect gearing was the problem with V6 3/4 and 1 tons GMC's. With 320lb torque @ 1600 rpm's, most should have been equipped with 3.54 ( came too late ) or 3.73's ( not offered by GM at the time ), not the 4.10's or 4.56's commonly found.
