On my 440 six pak engine, the casting date on the right side of the block is 10-30-69, yet on the top near the front of the intake the numbers are as follows: F440, then under that is: 12-10-HP. The casting number of the engine block is 2536430-7 and the VIN number stamped is 0B218114. Is 12-10 the date the engine was installed in the car? Does anyone have the car with VIN number 0B218114?

Is 12-10 the date the engine was installed in the car?

The date the engine was built.

The blocks were cast in batches (hence a casting date) and would sit around for a while before being used to make a complete engine (the date stamped on the pad).

Got it ! Thus the VIN number OB218114 would have been produced sometime in late December or early January. A few weeks after the engine was assembled on Dec 10th 1969.
