RE: engine codes
They are casting numbers. The first one is for a 1978 440 block; the next two are 383 blocks, from '59 to '71. There should be other codes on the engines that would indicate casting dates, newer ones will have VINs, others will have engine assembly details. If you can get some of those, it will further define what you're looking at.
