I have a 1981 Chevy Silverado 4wd 4spd crew cab for sale. This truck is almost impossible to find especially in the stock condition it is in. Anyone who knows anything about these square body trucks knows this is the holy grayly of it's class. One downside is it has a small block 400 rather than the stock 350 it is suppose to have. The motor starts and runs but it does pop and sputter through the exhaust. My plan was to put a new 350 motor in it and restore it to original. The floor boards are solid andin good shape as is the rest of the truck. The bed of the truck is in remarkable condition. This is a factory Silverado 4spd K30 3+3, I would be surprised if you could find another one for sale right now.
