The 302 shouldn't be any harder than in my 98? But your looking at a few grand probable and the wiring can be trickie unless u say the heck with it and go carb but even then a lot of issues. The 4.0 sohc motor has almost the same hp but the 302 has the torque. Mine came out of a 97 mountaineer so I took eng, tranny, awd transfer, pcm, wiring...and a lot of mods. But she sure does run good.
