440275-A should be the casting for the 352 block. 440971 would be the 374 casting. The casting date would indicate a 56 block but not sure if the A denotes 56 or some changes in the block from the 55s.

As Kev said, the first four numbers stamped on the flat surface just in front of the valley cover between the oil fill tube and left head will tell you what car it came from
