Would this engine be worth my time?

[mvfd70]

I just found out where there is an old Oldsmobile car sitting by a shed. The car itself is shot. More of the body is rusted away than is still in tact. I've been told that it is a 1965 Oldsmobile Eighty-eight or Nintey-eight. I've also been told that it has a big block 425. I'm hoping to talk to the guy that owns it and at least scavange the motor if it's worth anything.

If I can get it, would it be worth it? That would change my plans for my truck but if I can get a big block for the right price.....
