Stamps / Markings on Shelby Engines?

[CompFi]

I have two questions on identification stamps on Shelby American engines:

1. What stamp / marking identifies a particular Shelby engine?
2. What stamp / marking identifies a Shelby engine assembled by Yates racing?

And if anyone has examples of pictures depicting the above markings, I would be most appreciative. Particularly if anyone can direct me how to identify a Yates engine.

As always, thank you to this community for the great education.

Engine serial number stamped on the oil pan flange, near the rear of the block. A quick call to SA with the serial number and they can give you the history.

Vintage or modern Shelby engines?

I believe that it is current ownership of Shelby Engines that has been having Yates complete some engines. So, what is that? Specific to the past decade, maybe. I might not have that quite right, so someone here please correct me.

And again, any and all pictures of stamps on a Shelby engine will be greatly appreciated!

Thanks,
Brian
