I have a 96 gt that had the motor switched out by ford in the early part of 99 before I owned the car. I worked at a ford dealership for a while, and have driven many mustangs. Ive raced a 99+ mustang gt and it was neck and neck. Both auto's. Mine is bone stock except for removal of the air silencer. Any easy way to tell if I have a 99+ motor? thanks for your help.
