The big long number, on the back of the block, is a part number. The one you want to use is on the pad right in front of the drivers side cylinder head. This number will tell you everything you want to know about the history of the motor. Now on the back, if it is out of the car, just to the drivers side, on the bellhousing flange, you will see a letter, then 1, or 2 digits, followed by one more digit. The letter is the month. A is Jan., B is Feb., C is March, and so on. The next 1, or 2 numbers are the day of that month, and the last digit is the year.
