We took this out of my buddy's Seasport this spring when we upgraded him to a 5.7 MPI. Good compression, bearings look good, and it has a newer 2 bbl carb. It's really just a SBC 305, and can be dropped in a Mercruiser or Crusader installation, but you knew that. $725.00 or possible trade for something cool, like a Massey Ferguson or something. Maybe a handful of magic beans. PM me.
