360 Date Coding

The first pic of the block is from the drivers side showing the displacement of your motor being a 360. The other number came from the pass side showing the casting date of 10-?-72. It looks as thoug you do have a set of J heads. You didn't show the valves but i suspect they are the 1.88" intake and it would be 1.60" on the exhaust side. Maybe an early model 360. Any ideas on what your motor came out of. My books show 74 as the first year for a 360 to be offered in a Duster and 75 for the Dart. Could it have been a truck motor? A casting date of 10/72 would more than likely have gone in a 73 model auto.
