The injectors from the 01 will not plug into any of the v6 injector plugs on your truck. You need to find 92-99 V8 injectors, the yellow ford ones are even better. All of your other sensors need to be swapped from the v6 as they changed most of them between those years, also your valve cover filler and breather holes are probably in the wrong places, they jumped around over the years and aplications. Is you donor engine from a dakota, durango or van? If it is from a ram it will need an oil pan and pickup tube swap (you can use the V6 pickup tube but not the pan).
