5.3 head stud.
All these finding led me to believe it was a 3rd gen. So why does it take 4th gen studs.
So apon inspection I have an odd ball block its kind of a cross 3 to 4. It was my under standing that if the cam position sensor was in the rear of the block and not the front cover than it was a 3rd gen. I also have valley knock sensor’s and the motor does not have DOD
