360 Dodge

Looking at the lifter valley i wonder if you got a late 80s early 90s pre magnum block seeing that theres mounting holes for a roller cam lifter guide retainer plate.
I was wondering the same thing. It has the 5 bolt valve cover heads and the iron water pump that exits on the driver side. But then I saw the middle threaded holes and confusion set in. I’m new to Mopar, so this motor has the provisions to be a roller cam?
