I had no idea a 54, 5 window, hydramatic was that rare, I should treat her with more respect now that she's that special. She's already bringing our family closer together which I love. At Thanksgiving My son (43), grandson (11) and myself (old), 3 generations, all assisted in pulling out the existing motor. I have to say, my eyes watered up a couple of times..... I blamed it on dust.
The hydramatic is long gone and somewhere in her history, probably 55-60 years ago, someone hacked in an old 265 chevy small block. It was done with heavy channel and angle iron welded to the frame. Also some really cheesy motor mounts, I'm in the process of trying to get all that swap stuff out without messing up the frame. it's a challenge!
