318 Duster Rebuild - pros and cons of keeping matching numbers

I would never send it out . If you cannot drive it there meet the person and see the shop wait until you find a local shop you can trust. I heard to many horror stories on sending engines to get rebuilt.

You don't know if they are honest on what they find or what they have done. Seen so many rattle can rebuilds. You also want to hear it run on a run stand or Dyno. before paying for the job. If they find problems you can go look at what they discovered.

I had a A shop do a very expensive engine years ago. This is what I got back after start up in the car. I never got to back it out of the garage
