LT1 can certainly beworth the effort, cheap reliable and fast. But its much easier to have a donor car, LT1 or LS1, to make the swap happen because its really engine/wiring/trans at the least. The chassis’ are the same for all v6 and v8 cars between 93-02 (other than some small floorplan changes that affect trans crossmember choice). But the v6 transmissions wont work, so it will need to be a v8 trans that matches whether you get an LT1 or LS1 to put into it. The kmember bolts up to the car in the same places but the motor mounts and bolt holes are different. Computer is different, harness change for both dash and engine. The rear axles are all 7.625 10 bolts, so if you stick with the v6 version you just dont have posi. Suspensions are different but can work as is. v6 fuel pumps dont flow as much but Ive seen them work anyway. However 99+ went to plastic gas tanks with different setups, and LT1 and LS1 fuel pressures were different, so there are issues to resolve there.
So I guess it depends on what parts you have available and what you consider easy. Most wouldnt consider it easy, although it is all bolt on if you’re willing to change out most of the parts.
