Here's a little help:
Pic 1 of the stampings on the distributor pad:
8 - 1978 (see below)
T - Trenton engine plant
440 - self-explanatory
E - cast crank
HP - High Performance
Pic 2 - can't help you.
Pic 3 - block casting numbers:
4*13(?)*78 - casting date - April 13th, 1978. Is this out of an RV? That might explain the alternator bracket.
4006630-440-78 - Chrysler casting number
Pic 4 is not clear enough to make out the numbers, but they are the formal serial number for the block. It will often have the VIN of the vehicle it was originally installed in - likely an RV cab/chassis, given the casting date.
