On a BBC, there is an alphanumeric number machined on the pad in front of the passenger side cylinder head (move the alternator to see it) or above timing chain cover (use a mechanic's mirror and a strong flashlight). Also, there is a block casting number behind the driver's side head on the ledge adjacent to where the bellhousing bolts on. Again, use a mechanic's mirror and a strong flashlight.....
KD Tools , 2840 1-1/4 Inch Round Magnifying Mirror w/ Pocket Clip & Telescoping Handle
The number on the back of the block will identify the block casting and the alpha number on the front block deck or pad above the timing cover will tell you the original application of the motor.
