I would say the engine went into a 1970 car. There should be another set of numbers just above the oil pan rail on the passenger side with a number- a letter-and 6 numbers. This would be the last 8 of the VIN of the car it came in originally. According to the 10000 day calendar the engine was completed on 1/26/1970
Took me to long to finish my reply so now I'm late to the party....I hate that.....
