Anybody know what year/model this 302 came out of?

Ok, I just bought a 1984 full size Ford Bronco the other day from this guy here in town. He had an extra 302 motor just laying around in his garage that has been sitting there for about 4 years he said. It was all in pieces and he was wanting to get rid of it, so he packed it up in the back of the Bronco for me. Anyway, he doesn't know what the motor came out of or what year it is. The only numbers I can find for right now are as follow:

Block: DSVE-6015-ABA It also has a BA5 on there and the number 78 on the block. Does that mean the block was made in 78?

Heads: 8A6 for one and 8A7 for the other. They both have 78 stamped on the block too.

Any help you guys can give me would be greatly appreciated.
