Pete:

        I am not a real expert on this stuff, but I would strongly suggest
checking out the possibility of cleaning up this stuff, oiling it, and
storing it better.  Cylinder bores lightly-rusted should be cleanable with
honing, no problems, I would think.  The only critical areas of the
crankshaft are the machined journal surfaces.  If there is no pitting from
the rust, then a crocus cloth (or 600-800 wetordry paper) cleanup should be
OK.  Rust on counterweights and other non-machined surfaces should just be
wire-brushed.  Con rods are the same-the critical areas are the machined
bores at each end.  If not pitted, then a crocus-cloth cleanup on those
surfaces, along with wire brushing of the non-machined surfaces should be
OK.  This doesn't measure up to the "modern" expectation of absolute
perfection in every detail but the parts should be completely usable.  If
these procedures don't meet your expectations, then, at least check with
your local automotive machine shop about glass bead blasting, or some such,
before relegating everything to the scrap heap.  If, on the other hand,
anything is badly-pitted from the rust, then it probably should be
considered as just junk.  That's one man's opinion for what it is worth.

Regards,
David Kernberger
