If it's a 1949 WR motor I would expect the serial number to be stamped in a similar fashion to the example below:
In my serial number collection I have one example which is 49S++++ but that is a Big Twin Flathead and obvious reasons suggest it wasn't stamped at the H-D factory.
Could you post a partial photo of your serial number. Also have a look at the bottom of each crankcase half near the forward outer edges and let us know if you find anything stamped there.
And you could try contacting the people at beautyofspeed.com:

There's some racing bike info on their site. Eric

Quote: The cases are unstamped.
But does it look like the serial number boss was stamped at some point? Please post a clear photo of the serial number boss.
You mentioned the numbers by the seam are ?48 7998. They are called crankcase numbers or belly numbers and I'd like to know what that first character is. I suspect its going to be either 3 or 4 but Id like to see a clear photo.
Are there any casting numbers or casting date codes visible and if so can you post photos of them.
And theres something else to consider. Harley-Davidson built a 1949 Model S but it was a 125cc single cylinder bike. So if your title says 49S++++ then it's possible that title was originally for one of those single cylinder models and has nothing to do with the engine you have.
Im going offline for a day or two but I'll check in when I get back online. In the meantime please post those photos. Eric

CMC, what makes you think it's a WR motor as opposed to a WL or some other type of similar V-twin?
What are the belly numbers? Can you post photos of them please. And can you post photos of both sides of the engine.
