Champion engine identification

I am having some difficulty identifying the engine in my '50 2R5. The (stamped) engine number is 1R76168 which, as per the reference found at the SDC website

formatting link
indicates it is a "1949/1953 2R series Commercial 170'" unit. Am I correct in that this means blocks with this serial range were cast in '49 or '53?* Given that there is more than one year in which the block may have been cast, I am further assuming the casting number can be used an a secondary identifier...? Is this accurate? The (raised) casting number on my block is 524807-4, but I have yet to find any resrouce with which I can cross-reference this information. Provided the above assumptions are correct, I would like to know if there exists a list of Champion engine casting numbers that I may use to precisely identify my engine.

I hade made an effort to find this information myself (via searching the SDC and Truck Talk forums, and a.a.studebaker archives), but have come up empty handed thus far. I appreciate the help and information the NG denizens have provided me with thus far, and allow me to apologize in advance for the slew of questions I'm bound to post before my project is completed. :)

Thanks.

*I'm assuming that if these blocks were cast in '49 THROUGH '53, the notation on the list would read "1949-1953 2R series Commercial 170'" instead.

Really? Well I'll be damned. Methinks the notation on that page should be changed, then; as it is now, it's deceiving.

But what about pinning down the year? Is it possible to do so through engine casting numbers? Or, perhaps there's a record of what number ranges were produced in what years? Really, it's all academic; I don't HAVE to know, but am really curious.

Maybe I'll just cough up the cash for the Production Order from the museum....

Awesome! Thanks! How do you know that, by the way? Is that info available on the web? I'd like to know so if, in the future somebody asks me the same question I can help them out as you have me.

Casting numbers usually only give you a basic identification. For instance, 527807 was used from 1949 or 50 to 1954. Look for a date code on the distributor side of the block, near the top, probably near the front, but maybe near the rear. It will be four digits (X X XX). That is: a letter, a space, a number, a space, two numbers.
