Where can I go to find the original motor serial number for my car?

I just have to chime in.   When my Dad originally bought the car in the early 80's,  one of the selling features over another 280sl that was on the lot was that it had a factory replacement engine (with only 30,000 kilometres) that was a euro version engine correct for 1969/70.   

When I went to the Mercedes dealer to get parts several years back, they were initially confused so called out a mechanic from the back.   The old mechanic explained to the counter guy what the engine was and he gave me the thumbs up saying that the factory replacement engines were bullet proof.      To him it was just a part number like a brake caliper or a radiator.

I would say that to me, a factory replacement engine is more desirable than the original.   I got my car to drive rather than somebody looking for an alternative to Bonds or Gold.

I like teahead's argument.
It is very logical.
BUT, the market/buyers are not logical (or we would all be driving Toyota Camry's).
The market is what it is.

What’s wrong with the Camry? 🍿
Just kidding, sorry.

As for the matching numbers and all, I have a very simple approach to it. If you happen to have a car like that, excellent. On the same token I wouldn’t discount an example of a car or a solid project base where this was not a case. It’s all about appreciation and personal satisfaction. Can a perfect Pagoda sitting behind the glass bring more satisfaction than a well sorted weekend warrior? No way, at least not for me.

Would rather have an original hood than engine

You just need to watch Bob Waldman's great video that highlights "What to look for in buying a Pagoda". Not much emphasis on original engine blocks. I agree with Bob Waldman. For me, I would much rather see matching numbers in the original body panels. Original spot welds, no rust, no body repairs. A laser straight Pagoda with great door, hood and trunk gaps, for me, is much more valuable than a Bondo filled original block car. These are not Corvettes, where the engine block often determines the value. Condition is the key with Pagodas.

That being said, if having an original engine block floats your boat, go for it.

Funny about #s matching...

you hear about this all the time on Chevys etc.  However, that term will also included RE-STAMPED blocks!  So if buying a "#s matching" car, you must also ask them if that's the original engine or not.
