Big block identification

I have 4 455 blocks and I don’t know if any of them are w blocks or just run of the mill big blocks.

There is no such thing as a "w-block".

The first VIN derivative you posted is a 1974 motor installed in a car from Lansing. The other three are marine/industrial motors. No, there is no difference in the block from those used in passenger cars. The block casting numbers would also help.
