Finally got a Dart, been sitting a while...
pull plugs and look in there for rusty cylinders. IF they are clean fill with oil, prelube with a drill and turn the crank a few times with the plugs out. If it was rebuilt in 86, was the cam ever broken in? Assume it hasn't and run it like its not. Tough call: what would you do if you pulled the pan and you has some slight patina on the dry crank? Would you take it down to a bare block and start all over or just start it and blow the dust out? Id be so excited to start it Id just say F it, fill it and fire it!
