All, I've never been pleased with the power available from the 4.0 V6 in my 2001 Sport Trac. Since they put a 4.6 in 01 Explorers, could it be swapped over easily (bolt in) to Sport Tracs? Do you know of anyone who has done this swap? Also, what about the technology put forward for the 4.6 supercharged Adrenaline? Is any of that available for usage? Any and all help is greatly appreciated. Jeff
