I am more likely to believe you got a bad rebuild on your starter. The shop may be good, but they are most likely getting their stuff from china like everything else. And if the work ethic of most of the people I have worked with for the last 20 years or so is any indication, I wouldn't have that much faith in USA made parts either.(I can't believe the awful work that gets done that I have to clean up after) I don't know how long it has ran, but if you have something that tight it won't run long, and you would have large amounts of some sort of metal in the oil I would think. I mean if the guy before you was driving it and you have been driving it, I would tend to think it wasn't main bearings or piston clearances, I may be entirely wrong of course, but at least just drain the oil and see what you get. You can also have the starter tested for bad components. Your very good shop should be able to do that I used to know how to do that but its getting fuzzier each year.
