The block number is generally too vague to tell you much. You want the block stamping numbers located on the passenger side of the block where the head meets the block. Unless the block has been decked which will remove these stamped numbers, it will tell you the car model, year range, and other info. It may also have a partial VIN number stamped in.

These should help ID just exactly what you have and from where it came.
