I assume the cost has something to do with your decision.

Chevy used a four-speed manual transmissions with overdrive in half-ton and light 3/4 ton trucks 1981 - 1986. They show up fairly cheap. It's a New Process NP833 - Chevy RPO code MY6. Used parts catalogs usually show it as a "side cover" trans, and the HD four speed you have as the "top cover" trans.
It has a torque rating of 270 lb. ft., 1st gear - 3.09. 2nd gear - 1.67, 3rd gear - 1, and fourth OD - .73, and reverse - 3.

The later light-duty 5 speed - i.e. the NV3500 has an integral bellhousing and is rated for 300 lb. ft. of engine torque and a max. GVWR truck of 7200 lbs. Gear Ratio
1st 4.01
2nd 2.32
3rd 1.40
4th 1.00
5th 0.73
