ID THIS BLOCK

Good Day All
Acquired an engine that was alleged to be of 1966 vintage. The motor had all the machine work done, just never assembled. All the new parts were there and the price was reasonable $300.00 it also included a transmission.
I was skeptical when I saw it but purchased it anyway.
So far I have determined that the head (4104363) dates 81-87. The crank (4095246) dates to 81-87 The block, however, is a mystery. Here are some pics:View attachment 1716314656View attachment 1716314657View attachment 1716314659View attachment 1716314658View attachment 1716314661 More questions to follow once I figure this out.
Thanks to all who respond

The ID Stamping would seem to indicate a passenger car unit, '79 built March 9th. The pic You re-posted is the last of the VIN# of the vehicle it came out of....still kinda hard to see, at least on My phone, but You'd have to search for that VIN thru Chrysler Historical or some appropriate DMV records if possible.
