Find a good machine shop, and take the bare block and crank to him and ask "is this engine ok for a ring and bearing rebuild?" Tell them you just want an opinion,like Tech said. An honest shop will come back and tell you yes or no, then you can make a decision from there to just hone it, or bore, or whatever.

Even a simple re ring and bearing job should be preceeded by a hot tank, cam bearing, freeze plug, and hone job. This isn't terrible, costwise, and you will be starting with a clean slate. Also have them give you an opinion on if the crank can be used as is or needs polished or turned.
