ok so i had an early 04 motor that had a valve come apart a few months ago and smoke the motor. i have since gotten a new motor and began installing it. the "new" motor is and 04.5 motor. What are the differences in the motors? will i have issues running it with my old ecm because my truck is a 6 speed and the motor is out of an auto so i have to switch them. will it run alright?
