I currently own a 2004 (new body) 5.4 3V F150... I cracked one of my pistons and am having trouble finding the correct parts for the overhaul as far as the dealership... Would a 2004 5.4 3V piston from and Expy serve the same purpose? would it have the same compression ratio? Are they the same engines? if not then whats the difference.. Help please... This is my daily... So the more its in the garage the more i lose money... Thanks guys..

Also... If i were to swap engines, seeing that they produce the same torque and HP... is that possible or would there be some complications?
