Need help ID'ing a 302 block for a 66 mustang restomod
I am restoring a 66 mustang and my plan is to put a modern 302 motor with a carb. Since the car is a father son project we are trying to do this on a budget so my neighbor gave me a 302 block that his dad had laying around and I have no clue how to tell what year it is. Attached are all the markings I can find for it. Any help is greatly appreciated.
