I misunderstood - ONLY the OP's subject engine is stamped at the parting line - not both.

Transmission appears to be the original 727 to your car & won't have a partial VIN# stamping.

transmission PK2801543K (383 2bbl) 2442 (Thursday 4/4/68) 9524 (unit number)

Your Charger was built mid-April '68.
