Actually the Engine "Stamp" is on the Block itself, right in front of the Passenger Side Cylinder Head, which I believe is where you got it from. The Date from the FII9D Code is January, 19th. The "D" in the Code is for a 283 2-Barrel with a Powerglide Trans.
The Year of the Engine is on the Date Code on the back of the Block, but it can be hard to see with the engine still in the car. But if the engine appears to be all original, there are also Date Codes on the Heads, under the Valve Covers, as well as a Date on the Intake Manifold.
