I was under the impression from companies like Air Power that you can pay them $40K for a "new" factory remanufactured engine plus a refundable $20K core charge that you get back when you turn in your original. That way you can fly your own engine until your "new" engine is delivered and do a much faster swap.
That is what I did in November, 2020. I ordered a Lycoming Factory rebuild (from AirPower) for $32,700. I was considering keeping my old engine, overhauling it with my A&P, and preserving it as a ready spare (until I saw the Core charge from Lycoming of $17,400). Round trip freight was just under $1K. I was initially quoted an 11 week delivery, which progressively stretched to 14 weeks. Having it done by a good shop closer to me would have taken a month less, assuming no big issues.
I wanted to have a zero-time engine, so a Lycoming rebuild was the only way to go. Plus, during the long delay, I removed the old engine, had the prop governor and oil cooler overhauled, and did some other maintenance items on the airplane. The downside was you don't know the history of any of the parts in a rebuild, even if Lycoming does it, just that they meet new tolerances. If they had rebuilt mine, I would have known the history of the engine.
Anyway compared to the supply chain issues folks are dealing with today, I consider myself lucky...
