I found this block hiding under the back corner of a work bench on my late father's property. I don't know what the thing is, but I'm sure you guys can figure it out. . . There's a number stamped on the top front of the block (the "shiny" spot) that reads D44-86088 I apologize for the crappy cell phones pics. These are the only one's I got before the battery died.
Thanks guys. That would explain the heads and other assorted hemi parts I found in various places around the shop. There just may be a complete engine from all the bits and goodies I've found hidden around there.
