what has to be done to a 350 vortec from a 2wd out of a 97 truck to put it in a 4wd 98 gmc sierra
Might be a slight change in the oil pan and pickup tube and the accessory drive plate might be different but it should bolt right up. Double check the sensor plugs, there might be a connector change, if so just swap them out.
Just a matter of swapping any parts if necessary, '97 to '98 really shouldn't be much.
