Swapping out the stock motor for the 3.0L motor from the Taurus? I was reading the article in MM&FF where the SHO Shop did an SVT Tour and picked up like 60-70 wheel horsepower, not to mention the torque increase. The articl also stated that everything was a direct bolt-on. The heads only need minimal wprk (filling in extra coolant holes) for the swap. Anyway I just thought it seemed natural to swap a motor that would mate right up to everything you have. Wish us 4.6 guys had that kind luck with the 5.4
