Hello all,
So my truck has a GM replacement crate engine made in Mexico 10066036 which in my research is a 350 4 bolt main (confirmed that). My question lies in the fact that I do not know when it was made. There are the dots which I understand but this engine has a second set of dots you can see in the picture its the first set of dots, arrow pointing to the one dot. Can anyone decode the build date of this engine from the picture?
