Engine block (and transmission) VIN derivative(s) will match the VIN as per this/these examples if the car is an original numbers matching (OEM) vehicle as it rolled off the assembly line. The number "3" designates Oldsmobile division.

The date code for when the block was cast is back by the distributor. Its a julian date, so it will be a number between 1 and 365
