PUZZLER!!! My new motors a dog! what did I miss?

I don't think the 12/12 or the 6/12 install of the cam makes any difference at all. Remember the crank goes around twice for every time the cam goes around so it is a moot point. The next time around it would be at 6/12 if it was installed at 12/12. The thing I would be looking at is, was the correct mark used on the crank gear to time the crank and cam. There are to many marks on a Mopar small block crank gear and the wrong one can be used very easily.
