WTB: engine number 900880

I bought a 65, 911 #300717. I dont have the original engine. I'm looking for engine # 900880. Last seen in the Portland, OR area around 30 years ago.
The story is the owner at the time, now believed to be deceased had the engine rebuilt but couldnt afford to pay the bill so the mechanic got it.
Please get in touch if you have it or any leads
Thanks

is there a registry of lost engine? in other words anyone keeping track of cars without engines and engines with out numbers matching cars.
For example I have engine numbers: 902769 and 901635 that I would be willing to sell if someone has a c of a showing that they need either for their car.
