Look on the block in front of the passenger side head and find a group of numbers and letters stamped onto the deck. These will idntify what you have. The numbers will be something like [ VO113DZ] this is the code that you are looking for. Here is a website to help you decode your block...

If its a 350 the answer is no, its not from a 69 Z28. If its a 302 then ....well .... it could be... likely .... mostly.
