I scored a 440

I was at my friends beach place in Long Beach this weekend, his neighbor has had a old 70's motor home in the driveway for a long time. They were moving and were having a sale at the house.

They have always had cool stuff so i went to look, I looked in the motor home and it had one of those old Dodge truck auto trans shifters. I looked at the maufactures plaque, Made By Chrysler. HMMM, i looked underneath, Chrysler big block.

They said I could have it if i took the whole thing.

Does anyone know the specs on the engine and trans for one of those 440's found in those Chassis for those yrs? Is it worth getting or is it a hunk of junk?
